Overview

An API client for SQS. To construct a client, you need to configure a ‘:region` and `:credentials`.

client = Aws::SQS::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the [developer guide](/sdk-for-ruby/v3/developer-guide/setup-config.html).

See #initialize for a full list of supported configuration options.

#initialize(options) ⇒ Client

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :credentials (required, Aws::CredentialProvider)

    Your AWS credentials. This can be an instance of any one of the following classes:

    • ‘Aws::Credentials` - Used for configuring static, non-refreshing credentials.

    • ‘Aws::SharedCredentials` - Used for loading static credentials from a shared file, such as `~/.aws/config`.

    • ‘Aws::AssumeRoleCredentials` - Used when you need to assume a role.

    • ‘Aws::AssumeRoleWebIdentityCredentials` - Used when you need to assume a role after providing credentials via the web.

    • ‘Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an access token generated from `aws login`.

    • ‘Aws::ProcessCredentials` - Used for loading credentials from a process that outputs to stdout.

    • ‘Aws::InstanceProfileCredentials` - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • ‘Aws::ECSCredentials` - Used for loading credentials from instances running in ECS.

    • ‘Aws::CognitoIdentityCredentials` - Used for loading credentials from the Cognito Identity service.

    When ‘:credentials` are not configured directly, the following locations will be searched for credentials:

    • Aws.config`

    • The ‘:access_key_id`, `:secret_access_key`, and `:session_token` options.

    • ENV, ENV

    • ‘~/.aws/credentials`

    • ‘~/.aws/config`

    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of ‘Aws::InstanceProfileCredentails` or `Aws::ECSCredentials` to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV to true.

  • :region (required, String)

    The AWS region to connect to. The configured ‘:region` is used to determine the service `:endpoint`. When not passed, a default `:region` is searched for in the following locations:

  • :access_key_id (String)
  • :active_endpoint_cache (Boolean) — default: false

    When set to ‘true`, a thread polling for endpoints will be running in the background every 60 secs (default). Defaults to `false`.

  • :adaptive_retry_wait_to_fill (Boolean) — default: true

    Used only in ‘adaptive` retry mode. When true, the request will sleep until there is sufficent client side capacity to retry the request. When false, the request will raise a `RetryCapacityNotAvailableError` and will not retry instead of sleeping.

  • :client_side_monitoring (Boolean) — default: false

    When ‘true`, client-side metrics will be collected for all API requests from this client.

  • :client_side_monitoring_client_id (String) — default: ""

    Allows you to provide an identifier for this client which will be attached to all generated client side metrics. Defaults to an empty string.

  • :client_side_monitoring_host (String) — default: "127.0.0.1"

    Allows you to specify the DNS hostname or IPv4 or IPv6 address that the client side monitoring agent is running on, where client metrics will be published via UDP.

  • :client_side_monitoring_port (Integer) — default: 31000

    Required for publishing client metrics. The port that the client side monitoring agent is running on, where client metrics will be published via UDP.

  • :client_side_monitoring_publisher (Aws::ClientSideMonitoring::Publisher) — default: Aws::ClientSideMonitoring::Publisher

    Allows you to provide a custom client-side monitoring publisher class. By default, will use the Client Side Monitoring Agent Publisher.

  • :convert_params (Boolean) — default: true

    When ‘true`, an attempt is made to coerce request parameters into the required types.

  • :correct_clock_skew (Boolean) — default: true

    Used only in ‘standard` and adaptive retry modes. Specifies whether to apply a clock skew correction and retry requests with skewed client clocks.

  • :defaults_mode (String) — default: "legacy"

    See DefaultsModeConfiguration for a list of the accepted modes and the configuration defaults that are included.

  • :disable_host_prefix_injection (Boolean) — default: false

    Set to true to disable SDK automatically adding host prefix to default service endpoint when available.

  • :disable_request_compression (Boolean) — default: false

    When set to ‘true’ the request body will not be compressed for supported operations.

  • :endpoint (String, URI::HTTPS, URI::HTTP)

    Normally you should not configure the ‘:endpoint` option directly. This is normally constructed from the `:region` option. Configuring `:endpoint` is normally reserved for connecting to test or custom endpoints. The endpoint should be a URI formatted like:

    'http://example.com'
    'https://example.com'
    'http://example.com:123'
    
  • :endpoint_cache_max_entries (Integer) — default: 1000

    Used for the maximum threads in use for polling endpoints to be cached, defaults to 10.

  • :endpoint_cache_poll_interval (Integer) — default: 60

    When :endpoint_discovery and :active_endpoint_cache is enabled, Use this option to config the time interval in seconds for making requests fetching endpoints information. Defaults to 60 sec.

  • :endpoint_discovery (Boolean) — default: false

    When set to ‘true`, endpoint discovery will be enabled for operations when available.

  • :ignore_configured_endpoint_urls (Boolean)

    Setting to true disables use of endpoint URLs provided via environment variables and the shared configuration file.

  • :log_formatter (Aws::Log::Formatter) — default: Aws::Log::Formatter.default

    The log formatter.

  • :log_level (Symbol) — default: :info

    The log level to send messages to the ‘:logger` at.

  • :logger (Logger)

    The Logger instance to send log messages to. If this option is not set, logging will be disabled.

  • :max_attempts (Integer) — default: 3

    An integer representing the maximum number attempts that will be made for a single request, including the initial attempt. For example, setting this value to 5 will result in a request being retried up to 4 times. Used in ‘standard` and `adaptive` retry modes.

  • :profile (String) — default: "default"

    Used when loading credentials from the shared credentials file at HOME/.aws/credentials. When not specified, ‘default’ is used.

  • :request_min_compression_size_bytes (Integer) — default: 10240

    The minimum size in bytes that triggers compression for request bodies. The value must be non-negative integer value between 0 and 10485780 bytes inclusive.

  • :retry_backoff (Proc)

    The base delay in seconds used by the default backoff function. This option is only used in the ‘legacy` retry mode.

  • :retry_jitter (Symbol) — default: :none

    A delay randomiser function used by the default backoff function. Some predefined functions can be referenced by name - :none, :equal, :full, otherwise a Proc that takes and returns a number. This option is only used in the ‘legacy` retry mode.

    @see www.awsarchitectureblog.com/2015/03/backoff.html

  • :retry_limit (Integer) — default: 3

    The maximum number of times to retry failed requests. Only ~ 500 level server errors and certain ~ 400 level client errors are retried. Generally, these are throttling errors, data checksum errors, networking errors, timeout errors, auth errors, endpoint discovery, and errors from expired credentials. This option is only used in the ‘legacy` retry mode.

  • :retry_max_delay (Integer) — default: 0

    The maximum number of seconds to delay between retries (0 for no limit) used by the default backoff function. This option is only used in the ‘legacy` retry mode.

  • :retry_mode (String) — default: "legacy"

    Specifies which retry algorithm to use. Values are:

    • ‘legacy` - The pre-existing retry behavior. This is default value if no retry mode is provided.

    • ‘standard` - A standardized set of retry rules across the AWS SDKs. This includes support for retry quotas, which limit the number of unsuccessful retries a client can make.

    • ‘adaptive` - An experimental retry mode that includes all the functionality of `standard` mode along with automatic client side throttling. This is a provisional mode that may change behavior in the future.

  • :sdk_ua_app_id (String)

    A unique and opaque application ID that is appended to the User-Agent header as app/sdk_ua_app_id. It should have a maximum length of 50. This variable is sourced from environment variable AWS_SDK_UA_APP_ID or the shared config profile attribute sdk_ua_app_id.

  • :secret_access_key (String)
  • :session_token (String)
  • :simple_json (Boolean) — default: false

    Disables request parameter conversion, validation, and formatting. Also disable response data type conversions. This option is useful when you want to ensure the highest level of performance by avoiding overhead of walking request parameters and response data structures.

    When ‘:simple_json` is enabled, the request parameters hash must be formatted exactly as the DynamoDB API expects.

  • :stub_responses (Boolean) — default: false

    Causes the client to return stubbed responses. By default fake responses are generated and returned. You can specify the response data to return or errors to raise by calling ClientStubs#stub_responses. See ClientStubs for more information.

    ** Please note ** When response stubbing is enabled, no HTTP requests are made, and retries are disabled.

  • :token_provider (Aws::TokenProvider)

    A Bearer Token Provider. This can be an instance of any one of the following classes:

    • ‘Aws::StaticTokenProvider` - Used for configuring static, non-refreshing tokens.

    • ‘Aws::SSOTokenProvider` - Used for loading tokens from AWS SSO using an access token generated from `aws login`.

    When ‘:token_provider` is not configured directly, the `Aws::TokenProviderChain` will be used to search for tokens configured for your profile in shared configuration files.

  • :use_dualstack_endpoint (Boolean)

    When set to ‘true`, dualstack enabled endpoints (with `.aws` TLD) will be used if available.

  • :use_fips_endpoint (Boolean)

    When set to ‘true`, fips compatible endpoints will be used if available. When a `fips` region is used, the region is normalized and this config is set to `true`.

  • :validate_params (Boolean) — default: true

    When ‘true`, request parameters are validated before sending the request.

  • :verify_checksums (Boolean) — default: true

    When ‘true` MD5 checksums will be computed for messages sent to an SQS queue and matched against MD5 checksums returned by Amazon SQS. `Aws::Errors::Checksum` errors are raised for cases where checksums do not match.

  • :endpoint_provider (Aws::SQS::EndpointProvider)

    The endpoint provider used to resolve endpoints. Any object that responds to ‘#resolve_endpoint(parameters)` where `parameters` is a Struct similar to `Aws::SQS::EndpointParameters`

  • :http_continue_timeout (Float) — default: 1

    The number of seconds to wait for a 100-continue response before sending the request body. This option has no effect unless the request has “Expect” header set to “100-continue”. Defaults to ‘nil` which disables this behaviour. This value can safely be set per request on the session.

  • :http_idle_timeout (Float) — default: 5

    The number of seconds a connection is allowed to sit idle before it is considered stale. Stale connections are closed and removed from the pool before making a request.

  • :http_open_timeout (Float) — default: 15

    The default number of seconds to wait for response data. This value can safely be set per-request on the session.

  • :http_proxy (URI::HTTP, String)

    A proxy to send requests through. Formatted like ‘proxy.com:123’.

  • :http_read_timeout (Float) — default: 60

    The default number of seconds to wait for response data. This value can safely be set per-request on the session.

  • :http_wire_trace (Boolean) — default: false

    When ‘true`, HTTP debug output will be sent to the `:logger`.

  • :on_chunk_received (Proc)

    When a Proc object is provided, it will be used as callback when each chunk of the response body is received. It provides three arguments: the chunk, the number of bytes received, and the total number of bytes in the response (or nil if the server did not send a ‘content-length`).

  • :on_chunk_sent (Proc)

    When a Proc object is provided, it will be used as callback when each chunk of the request body is sent. It provides three arguments: the chunk, the number of bytes read from the body, and the total number of bytes in the body.

  • :raise_response_errors (Boolean) — default: true

    When ‘true`, response errors are raised.

  • :ssl_ca_bundle (String)

    Full path to the SSL certificate authority bundle file that should be used when verifying peer certificates. If you do not pass ‘:ssl_ca_bundle` or `:ssl_ca_directory` the the system default will be used if available.

  • :ssl_ca_directory (String)

    Full path of the directory that contains the unbundled SSL certificate authority files for verifying peer certificates. If you do not pass ‘:ssl_ca_bundle` or `:ssl_ca_directory` the the system default will be used if available.

#add_permission(params = {}) ⇒ Struct

Adds a permission to a queue for a specific [principal]. This allows sharing access to the queue.

When you create a queue, you have full control access rights for the queue. Only you, the owner of the queue, can grant or deny permissions to the queue. For more information about these permissions, see [Allow Developers to Write Messages to a Shared Queue] in the *Amazon SQS Developer Guide*.

<note markdown=“1”> * ‘AddPermission` generates a policy for you. You can use `

SetQueueAttributes ` to upload your policy. For more information,
see [Using Custom Policies with the Amazon SQS Access Policy
Language][3] in the *Amazon SQS Developer Guide*.
  • An Amazon SQS policy can have a maximum of seven actions per statement.

  • To remove the ability to change queue permissions, you must deny permission to the ‘AddPermission`, `RemovePermission`, and `SetQueueAttributes` actions in your IAM policy.

  • Amazon SQS ‘AddPermission` does not support adding a non-account principal.

</note>

<note markdown=“1”> Cross-account permissions don’t apply to this action. For more information, see [Grant cross-account permissions to a role and a username] in the *Amazon SQS Developer Guide*.

#cancel_message_move_task(params = {}) ⇒ Types::CancelMessageMoveTaskResult

Cancels a specified message movement task. A message movement can only be cancelled when the current status is RUNNING. Cancelling a message movement task does not revert the messages that have already been moved. It can only stop the messages that have not been moved yet.

<note markdown=“1”> * This action is currently limited to supporting message redrive from

[dead-letter queues (DLQs)][1] only. In this context, the source
queue is the dead-letter queue (DLQ), while the destination queue
can be the original source queue (from which the messages were
driven to the dead-letter-queue), or a custom destination queue.
  • Only one active message movement task is supported per queue at any given time.

end

#change_message_visibility(params = {}) ⇒ Struct

Changes the visibility timeout of a specified message in a queue to a new value. The default visibility timeout for a message is 30 seconds. The minimum is 0 seconds. The maximum is 12 hours. For more information, see [Visibility Timeout] in the *Amazon SQS Developer Guide*.

For example, if the default timeout for a queue is 60 seconds, 15 seconds have elapsed since you received the message, and you send a ChangeMessageVisibility call with ‘VisibilityTimeout` set to 10 seconds, the 10 seconds begin to count from the time that you make the `ChangeMessageVisibility` call. Thus, any attempt to change the visibility timeout or to delete that message 10 seconds after you initially change the visibility timeout (a total of 25 seconds) might result in an error.

An Amazon SQS message has three basic states:

  1. Sent to a queue by a producer.

  2. Received from the queue by a consumer.

  3. Deleted from the queue.

A message is considered to be stored after it is sent to a queue by a producer, but not yet received from the queue by a consumer (that is, between states 1 and 2). There is no limit to the number of stored messages. A message is considered to be *in flight* after it is received from a queue by a consumer, but not yet deleted from the queue (that is, between states 2 and 3). There is a limit to the number of in flight messages.

Limits that apply to in flight messages are unrelated to the unlimited number of stored messages.

For most standard queues (depending on queue traffic and message backlog), there can be a maximum of approximately 120,000 in flight messages (received from a queue by a consumer, but not yet deleted from the queue). If you reach this limit, Amazon SQS returns the ‘OverLimit` error message. To avoid reaching the limit, you should delete messages from the queue after they’re processed. You can also increase the number of queues you use to process your messages. To request a limit increase, [file a support request].

For FIFO queues, there can be a maximum of 20,000 in flight messages (received from a queue by a consumer, but not yet deleted from the queue). If you reach this limit, Amazon SQS returns no error messages.

If you attempt to set the ‘VisibilityTimeout` to a value greater than the maximum time left, Amazon SQS returns an error. Amazon SQS doesn’t automatically recalculate and increase the timeout to the maximum remaining time.

Unlike with a queue, when you change the visibility timeout for a

specific message the timeout value is applied immediately but isn’t saved in memory for that message. If you don’t delete a message after it is received, the visibility timeout for the message reverts to the original timeout value (not to the value you set using the ‘ChangeMessageVisibility` action) the next time the message is received.

Examples:

Request syntax with placeholder values


resp = client.change_message_visibility({
  queue_url: "String", # required
  receipt_handle: "String", # required
  visibility_timeout: 1, # required
})

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :queue_url (required, String)

    The URL of the Amazon SQS queue whose message’s visibility is changed.

    Queue URLs and names are case-sensitive.

  • :receipt_handle (required, String)

    The receipt handle associated with the message, whose visibility timeout is changed. This parameter is returned by the ‘ ReceiveMessage ` action.

  • :visibility_timeout (required, Integer)

    The new value for the message’s visibility timeout (in seconds). Values range: ‘0` to `43200`. Maximum: 12 hours.

Returns:

  • (Struct)

    Returns an empty response.

end

#change_message_visibility_batch(params = {}) ⇒ Types::ChangeMessageVisibilityBatchResult

Changes the visibility timeout of multiple messages. This is a batch version of ‘ ChangeMessageVisibility.` The result of the action on each message is reported individually in the response. You can send up to 10 ` ChangeMessageVisibility ` requests with each `ChangeMessageVisibilityBatch` action.

Because the batch request can result in a combination of successful and unsuccessful actions, you should check for batch errors even when the call returns an HTTP status code of ‘200`.

Examples:

resp.failed[0].message #=> String

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :queue_url (required, String)

    The URL of the Amazon SQS queue whose messages’ visibility is changed.

    Queue URLs and names are case-sensitive.

#create_queue(params = {}) ⇒ Types::CreateQueueResult

Creates a new standard or FIFO queue. You can pass one or more attributes in the request. Keep the following in mind:

  • If you don’t specify the ‘FifoQueue` attribute, Amazon SQS creates a standard queue.

    <note markdown=“1”> You can’t change the queue type after you create it and you can’t convert an existing standard queue into a FIFO queue. You must either create a new FIFO queue for your application or delete your existing standard queue and recreate it as a FIFO queue. For more information, see [Moving From a Standard Queue to a FIFO Queue] in the *Amazon SQS Developer Guide*.

    </note>
    
  • If you don’t provide a value for an attribute, the queue is created with the default value for the attribute.

  • If you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.

To successfully create a new queue, you must provide a queue name that adheres to the [limits related to queues] and is unique within the scope of your queues.

<note markdown=“1”> After you create a queue, you must wait at least one second after the queue is created to be able to use the queue.

</note>

To get the queue URL, use the ‘ GetQueueUrl ` action. ` GetQueueUrl ` requires only the `QueueName` parameter. be aware of existing queue names:

  • If you provide the name of an existing queue along with the exact names and values of all the queue’s attributes, ‘CreateQueue` returns the queue URL for the existing queue.

  • If the queue name, attribute names, or attribute values don’t match an existing queue, ‘CreateQueue` returns an error.

<note markdown=“1”> Cross-account permissions don’t apply to this action. For more information, see [Grant cross-account permissions to a role and a username] in the *Amazon SQS Developer Guide*.

    A map of attributes with their corresponding values.

    The following lists the names, descriptions, and values of the special request parameters that the ‘CreateQueue` action uses:

    • ‘DelaySeconds` – The length of time, in seconds, for which the delivery of all messages in the queue is delayed. Valid values: An integer from 0 to 900 seconds (15 minutes). Default: 0.

    • ‘MaximumMessageSize` – The limit of how many bytes a message can contain before Amazon SQS rejects it. Valid values: An integer from 1,024 bytes (1 KiB) to 262,144 bytes (256 KiB). Default: 262,144 (256 KiB).

    • ‘MessageRetentionPeriod` – The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer from 60 seconds (1 minute) to 1,209,600 seconds (14 days). Default: 345,600 (4 days). When you change a queue’s attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the Amazon SQS system. Changes made to the ‘MessageRetentionPeriod` attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if the `MessageRetentionPeriod` is reduced below the age of existing messages.

    • ‘Policy` – The queue’s policy. A valid Amazon Web Services policy. For more information about policy structure, see [Overview of Amazon Web Services IAM Policies] in the *IAM User Guide*.

    • ‘ReceiveMessageWaitTimeSeconds` – The length of time, in seconds, for which a ` ReceiveMessage ` action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0.

    • ‘VisibilityTimeout` – The visibility timeout for the queue, in seconds. Valid values: An integer from 0 to 43,200 (12 hours). Default: 30. For more information about the visibility timeout, see

      Visibility Timeout][2

      in the *Amazon SQS Developer Guide*.

    The following attributes apply only to [dead-letter queues:]

    • ‘RedrivePolicy` – The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object. The parameters are as follows:

      • ‘deadLetterTargetArn` – The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value of `maxReceiveCount` is exceeded.

      • ‘maxReceiveCount` – The number of times a message is delivered to the source queue before being moved to the dead-letter queue. Default: 10. When the `ReceiveCount` for a message exceeds the `maxReceiveCount` for a queue, Amazon SQS moves the message to the dead-letter-queue.

    • ‘RedriveAllowPolicy` – The string that includes the parameters for the permissions for the dead-letter queue redrive permission and which source queues can specify dead-letter queues as a JSON object. The parameters are as follows:

      • ‘redrivePermission` – The permission type that defines which source queues can specify the current queue as the dead-letter queue. Valid values are:

        • ‘allowAll` – (Default) Any source queues in this Amazon Web Services account in the same Region can specify this queue as the dead-letter queue.

        • ‘denyAll` – No source queues can specify this queue as the dead-letter queue.

        • ‘byQueue` – Only queues specified by the `sourceQueueArns` parameter can specify this queue as the dead-letter queue.

      • ‘sourceQueueArns` – The Amazon Resource Names (ARN)s of the source queues that can specify this queue as the dead-letter queue and redrive messages. You can specify this parameter only when the `redrivePermission` parameter is set to `byQueue`. You can specify up to 10 source queue ARNs. To allow more than 10 source queues to specify dead-letter queues, set the `redrivePermission` parameter to `allowAll`.

    <note markdown=“1”> The dead-letter queue of a FIFO queue must also be a FIFO queue. Similarly, the dead-letter queue of a standard queue must also be a standard queue.

    </note>
    

    The following attributes apply only to [server-side-encryption]:

    • ‘KmsMasterKeyId` – The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see [Key Terms]. While the alias of the Amazon Web Services managed CMK for Amazon SQS is always `alias/aws/sqs`, the alias of a custom CMK can, for example, be `alias/MyAlias `. For more examples, see [KeyId] in the *Key Management Service API Reference*.

    • ‘KmsDataKeyReusePeriodSeconds` – The length of time, in seconds, for which Amazon SQS can reuse a [data key] to encrypt or decrypt messages before calling KMS again. An integer representing seconds, between 60 seconds (1 minute) and 86,400 seconds (24 hours). Default: 300 (5 minutes). A shorter time period provides better security but results in more calls to KMS which might incur charges after Free Tier. For more information, see [How Does the Data Key Reuse Period Work?]

    • ‘SqsManagedSseEnabled` – Enables server-side queue encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, [SSE-KMS] or [SSE-SQS]).

    The following attributes apply only to [FIFO (first-in-first-out) queues]:

    • ‘FifoQueue` – Designates a queue as FIFO. Valid values are `true` and `false`. If you don’t specify the ‘FifoQueue` attribute, Amazon SQS creates a standard queue. You can provide this attribute only during queue creation. You can’t change it for an existing queue. When you set this attribute, you must also provide the ‘MessageGroupId` for your messages explicitly.

      For more information, see [FIFO queue logic] in the *Amazon SQS Developer Guide*.

    • ‘ContentBasedDeduplication` – Enables content-based deduplication. Valid values are `true` and `false`. For more information, see

      Exactly-once processing][13

      in the *Amazon SQS Developer Guide*.

      Note the following:

      • Every message must have a unique ‘MessageDeduplicationId`.

        • You may provide a ‘MessageDeduplicationId` explicitly.

        • If you aren’t able to provide a ‘MessageDeduplicationId` and you enable `ContentBasedDeduplication` for your queue, Amazon SQS uses a SHA-256 hash to generate the `MessageDeduplicationId` using the body of the message (but not the attributes of the message).

        • If you don’t provide a ‘MessageDeduplicationId` and the queue doesn’t have ‘ContentBasedDeduplication` set, the action fails with an error.

        • If the queue has ‘ContentBasedDeduplication` set, your `MessageDeduplicationId` overrides the generated one.

      • When ‘ContentBasedDeduplication` is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.

      • If you send one message with ‘ContentBasedDeduplication` enabled and then another message with a `MessageDeduplicationId` that is the same as the one generated for the first `MessageDeduplicationId`, the two messages are treated as duplicates and only one copy of the message is delivered.

    The following attributes apply only to [high throughput for FIFO queues]:

    • ‘DeduplicationScope` – Specifies whether message deduplication occurs at the message group or queue level. Valid values are `messageGroup` and `queue`.

    • ‘FifoThroughputLimit` – Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values are `perQueue` and `perMessageGroupId`. The `perMessageGroupId` value is allowed only when the value for `DeduplicationScope` is `messageGroup`.

    To enable high throughput for FIFO queues, do the following:

    • Set ‘DeduplicationScope` to `messageGroup`.

    • Set ‘FifoThroughputLimit` to `perMessageGroupId`.

    If you set these attributes to anything other than the values shown for enabling high throughput, normal throughput is in effect and deduplication occurs as specified.

    For information on throughput quotas, see [Quotas related to messages] in the *Amazon SQS Developer Guide*.

  • :tags (Hash<String,String>)

    Add cost allocation tags to the specified Amazon SQS queue. For an overview, see [Tagging Your Amazon SQS Queues] in the *Amazon SQS Developer Guide*.

    When you use queue tags, keep the following guidelines in mind:

    • Adding more than 50 tags to a queue isn’t recommended.

    • Tags don’t have any semantic meaning. Amazon SQS interprets tags as character strings.

    • Tags are case-sensitive.

    • A new tag with a key identical to that of an existing tag overwrites the existing tag.

    For a full list of tag restrictions, see [Quotas related to queues] in the *Amazon SQS Developer Guide*.

    <note markdown=“1”> To be able to tag a queue on creation, you must have the ‘sqs:CreateQueue` and `sqs:TagQueue` permissions.

    Cross-account permissions don't apply to this action. For more
    

    information, see [Grant cross-account permissions to a role and a username] in the *Amazon SQS Developer Guide*.

def create_queue(params = {}, options = {})
  req = build_request(:create_queue, params)
  req.send_request(options)
end

#delete_message(params = {}) ⇒ Struct

Deletes the specified message from the specified queue. To select the message to delete, use the ‘ReceiptHandle` of the message (not the `MessageId` which you receive when you send the message). Amazon SQS can delete a message from a queue even if a visibility timeout setting causes the message to be locked by another consumer. Amazon SQS automatically deletes messages left in a queue longer than the retention period configured for the queue.

<note markdown=“1”> The ‘ReceiptHandle` is associated with a *specific instance* of receiving a message. If you receive a message more than once, the `ReceiptHandle` is different each time you receive a message. When you use the `DeleteMessage` action, you must provide the most recently received `ReceiptHandle` for the message (otherwise, the request succeeds, but the message will not be deleted).

For standard queues, it is possible to receive a message even after

you delete it. This might happen on rare occasions if one of the servers which stores a copy of the message is unavailable when you send the request to delete the message. The copy remains on the server and might be returned to you during a subsequent receive request. You should ensure that your application is idempotent, so that receiving a message more than once does not cause issues.

#delete_message_batch(params = {}) ⇒ Types::DeleteMessageBatchResult

Deletes up to ten messages from the specified queue. This is a batch version of ‘ DeleteMessage.` The result of the action on each message is reported individually in the response.

Because the batch request can result in a combination of successful and unsuccessful actions, you should check for batch errors even when the call returns an HTTP status code of ‘200`.

Examples:

end

#delete_queue(params = {}) ⇒ Struct

Deletes the queue specified by the ‘QueueUrl`, regardless of the queue’s contents.

Be careful with the ‘DeleteQueue` action: When you delete a queue, any messages in the queue are no longer available.

When you delete a queue, the deletion process takes up to 60 seconds. Requests you send involving that queue during the 60 seconds might succeed. For example, a ‘ SendMessage ` request might succeed, but after 60 seconds the queue and the message you sent no longer exist.

When you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.

<note markdown=“1”> Cross-account permissions don’t apply to this action. For more information, see [Grant cross-account permissions to a role and a username] in the *Amazon SQS Developer Guide*.

The delete operation uses the HTTP `GET` verb.

Response structure


resp.attributes #=> Hash
resp.attributes["QueueAttributeName"] #=> String

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :queue_url (required, String)

    The URL of the Amazon SQS queue whose attribute information is retrieved.

    Queue URLs and names are case-sensitive.

  • :attribute_names (Array<String>)

    A list of attributes for which to retrieve information.

    The ‘AttributeNames` parameter is optional, but if you don’t specify values for this parameter, the request returns empty results.

    <note markdown=“1”> In the future, new attributes might be added. If you write code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.

    </note>
    

    The following attributes are supported:

    The ‘ApproximateNumberOfMessagesDelayed`, `ApproximateNumberOfMessagesNotVisible`, and `ApproximateNumberOfMessages` metrics may not achieve consistency until at least 1 minute after the producers stop sending messages. This period is required for the queue metadata to reach eventual consistency.

    • ‘All` – Returns all values.

    • ‘ApproximateNumberOfMessages` – Returns the approximate number of messages available for retrieval from the queue.

    • ‘ApproximateNumberOfMessagesDelayed` – Returns the approximate number of messages in the queue that are delayed and not available for reading immediately. This can happen when the queue is configured as a delay queue or when a message has been sent with a delay parameter.

    • ‘ApproximateNumberOfMessagesNotVisible` – Returns the approximate number of messages that are in flight. Messages are considered to be *in flight* if they have been sent to a client but have not yet been deleted or have not yet reached the end of their visibility window.

    • ‘CreatedTimestamp` – Returns the time when the queue was created in seconds ([epoch time]).

    • ‘DelaySeconds` – Returns the default delay on the queue in seconds.

    • ‘LastModifiedTimestamp` – Returns the time when the queue was last changed in seconds ([epoch time]).

    • ‘MaximumMessageSize` – Returns the limit of how many bytes a message can contain before Amazon SQS rejects it.

    • ‘MessageRetentionPeriod` – Returns the length of time, in seconds, for which Amazon SQS retains a message. When you change a queue’s attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the Amazon SQS system. Changes made to the ‘MessageRetentionPeriod` attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if the `MessageRetentionPeriod` is reduced below the age of existing messages.

    • ‘Policy` – Returns the policy of the queue.

    • ‘QueueArn` – Returns the Amazon resource name (ARN) of the queue.

    • ‘ReceiveMessageWaitTimeSeconds` – Returns the length of time, in seconds, for which the `ReceiveMessage` action waits for a message to arrive.

    • ‘VisibilityTimeout` – Returns the visibility timeout for the queue. For more information about the visibility timeout, see [Visibility Timeout] in the *Amazon SQS Developer Guide*.

    The following attributes apply only to [dead-letter queues:]

    • ‘RedrivePolicy` – The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object. The parameters are as follows:

      • ‘deadLetterTargetArn` – The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value of `maxReceiveCount` is exceeded.

      • ‘maxReceiveCount` – The number of times a message is delivered to the source queue before being moved to the dead-letter queue. Default: 10. When the `ReceiveCount` for a message exceeds the `maxReceiveCount` for a queue, Amazon SQS moves the message to the dead-letter-queue.

    • ‘RedriveAllowPolicy` – The string that includes the parameters for the permissions for the dead-letter queue redrive permission and which source queues can specify dead-letter queues as a JSON object. The parameters are as follows:

      • ‘redrivePermission` – The permission type that defines which source queues can specify the current queue as the dead-letter queue. Valid values are:

        • ‘allowAll` – (Default) Any source queues in this Amazon Web Services account in the same Region can specify this queue as the dead-letter queue.

        • ‘denyAll` – No source queues can specify this queue as the dead-letter queue.

        • ‘byQueue` – Only queues specified by the `sourceQueueArns` parameter can specify this queue as the dead-letter queue.

      • ‘sourceQueueArns` – The Amazon Resource Names (ARN)s of the source queues that can specify this queue as the dead-letter queue and redrive messages. You can specify this parameter only when the `redrivePermission` parameter is set to `byQueue`. You can specify up to 10 source queue ARNs. To allow more than 10 source queues to specify dead-letter queues, set the `redrivePermission` parameter to `allowAll`.

    <note markdown=“1”> The dead-letter queue of a FIFO queue must also be a FIFO queue. Similarly, the dead-letter queue of a standard queue must also be a standard queue.

    </note>
    

    The following attributes apply only to [server-side-encryption]:

    • ‘KmsMasterKeyId` – Returns the ID of an Amazon Web Services managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see [Key Terms].

    • ‘KmsDataKeyReusePeriodSeconds` – Returns the length of time, in seconds, for which Amazon SQS can reuse a data key to encrypt or decrypt messages before calling KMS again. For more information, see [How Does the Data Key Reuse Period Work?].

    • ‘SqsManagedSseEnabled` – Returns information about whether the queue is using SSE-SQS encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, [SSE-KMS] or [SSE-SQS]).

    The following attributes apply only to [FIFO (first-in-first-out) queues]:

    The following attributes apply only to [high throughput for FIFO queues]:

    • ‘DeduplicationScope` – Specifies whether message deduplication occurs at the message group or queue level. Valid values are `messageGroup` and `queue`.

    • ‘FifoThroughputLimit` – Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values are `perQueue` and `perMessageGroupId`. The `perMessageGroupId` value is allowed only when the value for `DeduplicationScope` is `messageGroup`.

    To enable high throughput for FIFO queues, do the following:

    • Set ‘DeduplicationScope` to `messageGroup`.

    • Set ‘FifoThroughputLimit` to `perMessageGroupId`.

    If you set these attributes to anything other than the values shown for enabling high throughput, normal throughput is in effect and deduplication occurs as specified.

#list_dead_letter_source_queues(params = {}) ⇒ Types::ListDeadLetterSourceQueuesResult

Returns a list of your queues that have the ‘RedrivePolicy` queue attribute configured with a dead-letter queue.

The ‘ListDeadLetterSourceQueues` methods supports pagination. Set parameter `MaxResults` in the request to specify the maximum number of results to be returned in the response.

end

#purge_queue(params = {}) ⇒ Struct

Deletes available messages in a queue (including in-flight messages) specified by the ‘QueueURL` parameter.

When you use the ‘PurgeQueue` action, you can’t retrieve any messages deleted from a queue.

The message deletion process takes up to 60 seconds. We recommend

waiting for 60 seconds regardless of your queue’s size.

Messages sent to the queue before you call ‘PurgeQueue` might be received but are deleted within the next minute.

Messages sent to the queue after you call ‘PurgeQueue` might be deleted while the queue is being purged.

Examples:

Request syntax with placeholder values


resp = client.purge_queue({
  queue_url: "String", # required
})

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :queue_url (required, String)

    The URL of the queue from which the ‘PurgeQueue` action deletes messages.

    Queue URLs and names are case-sensitive.

Returns:

  • (Struct)

    Returns an empty response.

#receive_message(params = {}) ⇒ Types::ReceiveMessageResult

Retrieves one or more messages (up to 10), from the specified queue. Using the ‘WaitTimeSeconds` parameter enables long-poll support. For more information, see [Amazon SQS Long Polling] in the *Amazon SQS Developer Guide*.

Short poll is the default behavior where a weighted random set of machines is sampled on a ‘ReceiveMessage` call. Thus, only the messages on the sampled machines are returned. If the number of messages in the queue is small (fewer than 1,000), you most likely get fewer messages than you requested per `ReceiveMessage` call. If the number of messages in the queue is extremely small, you might not receive any messages in a particular `ReceiveMessage` response. If this happens, repeat the request.

For each message returned, the response includes the following:

  • The message body.

  • An MD5 digest of the message body. For information about MD5, see [RFC1321].

  • The ‘MessageId` you received when you sent the message to the queue.

  • The receipt handle.

  • The message attributes.

  • An MD5 digest of the message attributes.

The receipt handle is the identifier you must provide when deleting the message. For more information, see [Queue and Message Identifiers] in the *Amazon SQS Developer Guide*.

You can provide the ‘VisibilityTimeout` parameter in your request. The parameter is applied to the messages that Amazon SQS returns in the response. If you don’t include the parameter, the overall visibility timeout for the queue is used for the returned messages. For more information, see [Visibility Timeout] in the *Amazon SQS Developer Guide*.

A message that isn’t deleted or a message whose visibility isn’t extended before the visibility timeout expires counts as a failed receive. Depending on the configuration of the queue, the message might be sent to the dead-letter queue.

<note markdown=“1”> In the future, new attributes might be added. If you write code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :queue_url (required, String)

    The URL of the Amazon SQS queue from which messages are received.

    Queue URLs and names are case-sensitive.

  • :attribute_names (Array<String>)

    This parameter has been deprecated but will be supported for backward compatibility. To provide attribute names, you are encouraged to use ‘MessageSystemAttributeNames`.

    A list of attributes that need to be returned along with each message. These attributes include:

    • ‘All` – Returns all values.

    • ‘ApproximateFirstReceiveTimestamp` – Returns the time the message was first received from the queue ([epoch time] in milliseconds).

    • ‘ApproximateReceiveCount` – Returns the number of times a message has been received across all queues but not deleted.

    • ‘AWSTraceHeader` – Returns the X-Ray trace header string.

    • ‘SenderId`

      • For a user, returns the user ID, for example ‘ABCDEFGHI1JKLMNOPQ23R`.

      • For an IAM role, returns the IAM role ID, for example ‘ABCDE1F2GH3I4JK5LMNOP:i-a123b456`.

    • ‘SentTimestamp` – Returns the time the message was sent to the queue ([epoch time] in milliseconds).

    • ‘SqsManagedSseEnabled` – Enables server-side queue encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, [SSE-KMS] or [SSE-SQS]).

    • ‘MessageDeduplicationId` – Returns the value provided by the producer that calls the ` SendMessage ` action.

    • ‘MessageGroupId` – Returns the value provided by the producer that calls the ` SendMessage ` action. Messages with the same `MessageGroupId` are returned in sequence.

    • ‘SequenceNumber` – Returns the value provided by Amazon SQS.

  • :message_system_attribute_names (Array<String>)

    A list of attributes that need to be returned along with each message. These attributes include:

    • ‘All` – Returns all values.

    • ‘ApproximateFirstReceiveTimestamp` – Returns the time the message was first received from the queue ([epoch time] in milliseconds).

    • ‘ApproximateReceiveCount` – Returns the number of times a message has been received across all queues but not deleted.

    • ‘AWSTraceHeader` – Returns the X-Ray trace header string.

    • ‘SenderId`

      • For a user, returns the user ID, for example ‘ABCDEFGHI1JKLMNOPQ23R`.

      • For an IAM role, returns the IAM role ID, for example ‘ABCDE1F2GH3I4JK5LMNOP:i-a123b456`.

    • ‘SentTimestamp` – Returns the time the message was sent to the queue ([epoch time] in milliseconds).

    • ‘SqsManagedSseEnabled` – Enables server-side queue encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, [SSE-KMS] or [SSE-SQS]).

    • ‘MessageDeduplicationId` – Returns the value provided by the producer that calls the ` SendMessage ` action.

    • ‘MessageGroupId` – Returns the value provided by the producer that calls the ` SendMessage ` action. Messages with the same `MessageGroupId` are returned in sequence.

    • ‘SequenceNumber` – Returns the value provided by Amazon SQS.

    [1]: en.wikipedia.org/wiki/Unix_time [2]: docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-configure-sse-existing-queue.html [3]: docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-configure-sqs-sse-queue.html

  • :message_attribute_names (Array<String>)

    The name of the message attribute, where N is the index.

    • The name can contain alphanumeric characters and the underscore (‘_`), hyphen (`-`), and period (`.`).

    • The name is case-sensitive and must be unique among all attribute names for the message.

    • The name must not start with AWS-reserved prefixes such as ‘AWS.` or `Amazon.` (or any casing variants).

    • The name must not start or end with a period (‘.`), and it should not have periods in succession (`..`).

    • The name can be up to 256 characters long.

    When using ‘ReceiveMessage`, you can send a list of attribute names to receive, or you can return all of the attributes by specifying `All` or `.*` in your request. You can also use all message attributes starting with a prefix, for example `bar.*`.

  • :max_number_of_messages (Integer)

    The maximum number of messages to return. Amazon SQS never returns more messages than this value (however, fewer messages might be returned). Valid values: 1 to 10. Default: 1.

  • :visibility_timeout (Integer)

    The duration (in seconds) that the received messages are hidden from subsequent retrieve requests after being retrieved by a ‘ReceiveMessage` request.

  • :wait_time_seconds (Integer)

    The duration (in seconds) for which the call waits for a message to arrive in the queue before returning. If a message is available, the call returns sooner than ‘WaitTimeSeconds`. If no messages are available and the wait time expires, the call does not return a message list.

    To avoid HTTP errors, ensure that the HTTP response timeout for ‘ReceiveMessage` requests is longer than the `WaitTimeSeconds` parameter. For example, with the Java SDK, you can set HTTP transport settings using the [ NettyNioAsyncHttpClient] for asynchronous clients, or the [ ApacheHttpClient] for synchronous clients.

    [1]: sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/http/nio/netty/NettyNioAsyncHttpClient.html [2]: sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/http/apache/ApacheHttpClient.html

  • :receive_request_attempt_id (String)

    This parameter applies only to FIFO (first-in-first-out) queues.

    The token used for deduplication of ‘ReceiveMessage` calls. If a networking issue occurs after a `ReceiveMessage` action, and instead of a response you receive a generic error, it is possible to retry the same action with an identical `ReceiveRequestAttemptId` to retrieve the same set of messages, even if their visibility timeout has not yet expired.

    • You can use ‘ReceiveRequestAttemptId` only for 5 minutes after a `ReceiveMessage` action.

    • When you set ‘FifoQueue`, a caller of the `ReceiveMessage` action can provide a `ReceiveRequestAttemptId` explicitly.

    • It is possible to retry the ‘ReceiveMessage` action with the same `ReceiveRequestAttemptId` if none of the messages have been modified (deleted or had their visibility changes).

    • During a visibility timeout, subsequent calls with the same ‘ReceiveRequestAttemptId` return the same messages and receipt handles. If a retry occurs within the deduplication interval, it resets the visibility timeout. For more information, see [Visibility Timeout] in the *Amazon SQS Developer Guide*.

      If a caller of the ‘ReceiveMessage` action still processes messages when the visibility timeout expires and messages become visible, another worker consuming from the same queue can receive the same messages and therefore process duplicates. Also, if a consumer whose message processing time is longer than the visibility timeout tries to delete the processed messages, the action fails with an error.

      To mitigate this effect, ensure that your application observes a
      

      safe threshold before the visibility timeout expires and extend the visibility timeout as necessary.

    • While messages with a particular ‘MessageGroupId` are invisible, no more messages belonging to the same `MessageGroupId` are returned until the visibility timeout expires. You can still receive messages with another `MessageGroupId` as long as it is also visible.

    • If a caller of ‘ReceiveMessage` can’t track the ‘ReceiveRequestAttemptId`, no retries work until the original visibility timeout expires. As a result, delays might occur but the messages in the queue remain in a strict order.

    The maximum length of ‘ReceiveRequestAttemptId` is 128 characters. `ReceiveRequestAttemptId` can contain alphanumeric characters (`a-z`, `A-Z`, `0-9`) and punctuation (“ !“#$%&’()*+,-./:;<=>?@[]^_`{|}~ “).

    For best practices of using ‘ReceiveRequestAttemptId`, see [Using the ReceiveRequestAttemptId Request Parameter] in the *Amazon SQS Developer Guide*.

  • :delay_seconds (Integer)

    The length of time, in seconds, for which to delay a specific message. Valid values: 0 to 900. Maximum: 15 minutes. Messages with a positive ‘DelaySeconds` value become available for processing after the delay period is finished. If you don’t specify a value, the default value for the queue applies.

    <note markdown=“1”> When you set ‘FifoQueue`, you can’t set ‘DelaySeconds` per message. You can set this parameter only on a queue level.

    </note>
    
  • :message_attributes (Hash<String,Types::MessageAttributeValue>)

    Each message attribute consists of a ‘Name`, `Type`, and `Value`. For more information, see [Amazon SQS message attributes] in the *Amazon SQS Developer Guide*.

    [1]: docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-message-metadata.html#sqs-message-attributes

  • :message_system_attributes (Hash<String,Types::MessageSystemAttributeValue>)

    The message system attribute to send. Each message system attribute consists of a ‘Name`, `Type`, and `Value`.

    • Currently, the only supported message system attribute is ‘AWSTraceHeader`. Its type must be `String` and its value must be a correctly formatted X-Ray trace header string.

    • The size of a message system attribute doesn’t count towards the total size of a message.

  • :message_deduplication_id (String)

    This parameter applies only to FIFO (first-in-first-out) queues.

    The token used for deduplication of sent messages. If a message with a particular ‘MessageDeduplicationId` is sent successfully, any messages sent with the same `MessageDeduplicationId` are accepted successfully but aren’t delivered during the 5-minute deduplication interval. For more information, see [ Exactly-once processing] in the *Amazon SQS Developer Guide*.

    • Every message must have a unique ‘MessageDeduplicationId`,

      • You may provide a ‘MessageDeduplicationId` explicitly.

      • If you aren’t able to provide a ‘MessageDeduplicationId` and you enable `ContentBasedDeduplication` for your queue, Amazon SQS uses a SHA-256 hash to generate the `MessageDeduplicationId` using the body of the message (but not the attributes of the message).

      • If you don’t provide a ‘MessageDeduplicationId` and the queue doesn’t have ‘ContentBasedDeduplication` set, the action fails with an error.

      • If the queue has ‘ContentBasedDeduplication` set, your `MessageDeduplicationId` overrides the generated one.

    • When ‘ContentBasedDeduplication` is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.

    • If you send one message with ‘ContentBasedDeduplication` enabled and then another message with a `MessageDeduplicationId` that is the same as the one generated for the first `MessageDeduplicationId`, the two messages are treated as duplicates and only one copy of the message is delivered.

    <note markdown=“1”> The ‘MessageDeduplicationId` is available to the consumer of the message (this can be useful for troubleshooting delivery issues).

    If a message is sent successfully but the acknowledgement is lost and
    

    the message is resent with the same ‘MessageDeduplicationId` after the deduplication interval, Amazon SQS can’t detect duplicate messages.

    Amazon SQS continues to keep track of the message deduplication ID
    

    even after the message is received and deleted.

    </note>
    

    The maximum length of ‘MessageDeduplicationId` is 128 characters. `MessageDeduplicationId` can contain alphanumeric characters (`a-z`, `A-Z`, `0-9`) and punctuation (“ !“#$%&’()*+,-./:;<=>?@[]^_`{|}~ “).

    For best practices of using ‘MessageDeduplicationId`, see [Using the MessageDeduplicationId Property] in the *Amazon SQS Developer Guide*.

  • :message_group_id (String)

    This parameter applies only to FIFO (first-in-first-out) queues.

    The tag that specifies that a message belongs to a specific message group. Messages that belong to the same message group are processed in a FIFO manner (however, messages in different message groups might be processed out of order). To interleave multiple ordered streams within a single queue, use ‘MessageGroupId` values (for example, session data for multiple users). In this scenario, multiple consumers can process the queue, but the session data of each user is processed in a FIFO fashion.

    • You must associate a non-empty ‘MessageGroupId` with a message. If you don’t provide a ‘MessageGroupId`, the action fails.

    • ‘ReceiveMessage` might return messages with multiple `MessageGroupId` values. For each `MessageGroupId`, the messages are sorted by time sent. The caller can’t specify a ‘MessageGroupId`.

    The maximum length of ‘MessageGroupId` is 128 characters. Valid values: alphanumeric characters and punctuation “ (!“#$%&’()*+,-./:;<=>?@[]^_`{|}~) “.

    For best practices of using ‘MessageGroupId`, see [Using the MessageGroupId Property] in the *Amazon SQS Developer Guide*.

    ‘MessageGroupId` is required for FIFO queues. You can’t use it for Standard queues.

end

#send_message_batch(params = {}) ⇒ Types::SendMessageBatchResult

You can use ‘SendMessageBatch` to send up to 10 messages to the specified queue by assigning either identical or different values to each message (or by not assigning values at all). This is a batch version of ` SendMessage.` For a FIFO queue, multiple messages within a single batch are enqueued in the order they are sent.

The result of sending each message is reported individually in the response. Because the batch request can result in a combination of successful and unsuccessful actions, you should check for batch errors even when the call returns an HTTP status code of ‘200`.

The maximum allowed individual message size and the maximum total payload size (the sum of the individual lengths of all of the batched messages) are both 256 KiB (262,144 bytes).

A message can include only XML, JSON, and unformatted text. The following Unicode characters are allowed:

`#x9` \| `#xA` \| `#xD` \| `#x20` to `#xD7FF` \| `#xE000` to `#xFFFD`

| ‘#x10000` to `#x10FFFF`

Any characters not included in this list will be rejected. For more

information, see the [W3C specification for characters].

If you don’t specify the ‘DelaySeconds` parameter for an entry, Amazon SQS uses the default value for the queue.

#set_queue_attributes(params = {}) ⇒ Struct

Sets the value of one or more queue attributes, like a policy. When you change a queue’s attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the Amazon SQS system. Changes made to the ‘MessageRetentionPeriod` attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if the `MessageRetentionPeriod` is reduced below the age of existing messages.

<note markdown=“1”> * In the future, new attributes might be added. If you write code that

calls this action, we recommend that you structure your code so that
it can handle new attributes gracefully.
  • Cross-account permissions don’t apply to this action. For more information, see [Grant cross-account permissions to a role and a username] in the *Amazon SQS Developer Guide*.

  • To remove the ability to change queue permissions, you must deny permission to the ‘AddPermission`, `RemovePermission`, and `SetQueueAttributes` actions in your IAM policy.

Examples:

Request syntax with placeholder values


resp = client.set_queue_attributes({
  queue_url: "String", # required
  attributes: { # required
    "All" => "String",
  },
})

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :queue_url (required, String)

    The URL of the Amazon SQS queue whose attributes are set.

    Queue URLs and names are case-sensitive.

  • :attributes (required, Hash<String,String>)

    A map of attributes to set.

    The following lists the names, descriptions, and values of the special request parameters that the ‘SetQueueAttributes` action uses:

    • ‘DelaySeconds` – The length of time, in seconds, for which the delivery of all messages in the queue is delayed. Valid values: An integer from 0 to 900 (15 minutes). Default: 0.

    • ‘MaximumMessageSize` – The limit of how many bytes a message can contain before Amazon SQS rejects it. Valid values: An integer from 1,024 bytes (1 KiB) up to 262,144 bytes (256 KiB). Default: 262,144 (256 KiB).

    • ‘MessageRetentionPeriod` – The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer representing seconds, from 60 (1 minute) to 1,209,600 (14 days). Default: 345,600 (4 days). When you change a queue’s attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the Amazon SQS system. Changes made to the ‘MessageRetentionPeriod` attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if the `MessageRetentionPeriod` is reduced below the age of existing messages.

    • ‘Policy` – The queue’s policy. A valid Amazon Web Services policy. For more information about policy structure, see [Overview of Amazon Web Services IAM Policies] in the *Identity and Access Management User Guide*.

    • ‘ReceiveMessageWaitTimeSeconds` – The length of time, in seconds, for which a ` ReceiveMessage ` action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0.

    • ‘VisibilityTimeout` – The visibility timeout for the queue, in seconds. Valid values: An integer from 0 to 43,200 (12 hours). Default: 30. For more information about the visibility timeout, see

      Visibility Timeout][2

      in the *Amazon SQS Developer Guide*.

    The following attributes apply only to [dead-letter queues:]

    • ‘RedrivePolicy` – The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object. The parameters are as follows:

      • ‘deadLetterTargetArn` – The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value of `maxReceiveCount` is exceeded.

      • ‘maxReceiveCount` – The number of times a message is delivered to the source queue before being moved to the dead-letter queue. Default: 10. When the `ReceiveCount` for a message exceeds the `maxReceiveCount` for a queue, Amazon SQS moves the message to the dead-letter-queue.

    • ‘RedriveAllowPolicy` – The string that includes the parameters for the permissions for the dead-letter queue redrive permission and which source queues can specify dead-letter queues as a JSON object. The parameters are as follows:

      • ‘redrivePermission` – The permission type that defines which source queues can specify the current queue as the dead-letter queue. Valid values are:

        • ‘allowAll` – (Default) Any source queues in this Amazon Web Services account in the same Region can specify this queue as the dead-letter queue.

        • ‘denyAll` – No source queues can specify this queue as the dead-letter queue.

        • ‘byQueue` – Only queues specified by the `sourceQueueArns` parameter can specify this queue as the dead-letter queue.

      • ‘sourceQueueArns` – The Amazon Resource Names (ARN)s of the source queues that can specify this queue as the dead-letter queue and redrive messages. You can specify this parameter only when the `redrivePermission` parameter is set to `byQueue`. You can specify up to 10 source queue ARNs. To allow more than 10 source queues to specify dead-letter queues, set the `redrivePermission` parameter to `allowAll`.

    <note markdown=“1”> The dead-letter queue of a FIFO queue must also be a FIFO queue. Similarly, the dead-letter queue of a standard queue must also be a standard queue.

    </note>
    

    The following attributes apply only to [server-side-encryption]:

    • ‘KmsMasterKeyId` – The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see [Key Terms]. While the alias of the AWS-managed CMK for Amazon SQS is always `alias/aws/sqs`, the alias of a custom CMK can, for example, be `alias/MyAlias `. For more examples, see

      KeyId][6

      in the *Key Management Service API Reference*.

    • ‘KmsDataKeyReusePeriodSeconds` – The length of time, in seconds, for which Amazon SQS can reuse a [data key] to encrypt or decrypt messages before calling KMS again. An integer representing seconds, between 60 seconds (1 minute) and 86,400 seconds (24 hours). Default: 300 (5 minutes). A shorter time period provides better security but results in more calls to KMS which might incur charges after Free Tier. For more information, see [How Does the Data Key Reuse Period Work?].

    • ‘SqsManagedSseEnabled` – Enables server-side queue encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, [SSE-KMS] or [SSE-SQS]).

    The following attribute applies only to [FIFO (first-in-first-out) queues]:

    • ‘ContentBasedDeduplication` – Enables content-based deduplication. For more information, see [Exactly-once processing] in the *Amazon SQS Developer Guide*. Note the following:

      • Every message must have a unique ‘MessageDeduplicationId`.

        • You may provide a ‘MessageDeduplicationId` explicitly.

        • If you aren’t able to provide a ‘MessageDeduplicationId` and you enable `ContentBasedDeduplication` for your queue, Amazon SQS uses a SHA-256 hash to generate the `MessageDeduplicationId` using the body of the message (but not the attributes of the message).

        • If you don’t provide a ‘MessageDeduplicationId` and the queue doesn’t have ‘ContentBasedDeduplication` set, the action fails with an error.

        • If the queue has ‘ContentBasedDeduplication` set, your `MessageDeduplicationId` overrides the generated one.

      • When ‘ContentBasedDeduplication` is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.

      • If you send one message with ‘ContentBasedDeduplication` enabled and then another message with a `MessageDeduplicationId` that is the same as the one generated for the first `MessageDeduplicationId`, the two messages are treated as duplicates and only one copy of the message is delivered.

    The following attributes apply only to [high throughput for FIFO queues]:

    • ‘DeduplicationScope` – Specifies whether message deduplication occurs at the message group or queue level. Valid values are `messageGroup` and `queue`.

    • ‘FifoThroughputLimit` – Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values are `perQueue` and `perMessageGroupId`. The `perMessageGroupId` value is allowed only when the value for `DeduplicationScope` is `messageGroup`.

    To enable high throughput for FIFO queues, do the following:

    • Set ‘DeduplicationScope` to `messageGroup`.

    • Set ‘FifoThroughputLimit` to `perMessageGroupId`.

    If you set these attributes to anything other than the values shown for enabling high throughput, normal throughput is in effect and deduplication occurs as specified.

    For information on throughput quotas, see [Quotas related to messages] in the *Amazon SQS Developer Guide*.

#start_message_move_task(params = {}) ⇒ Types::StartMessageMoveTaskResult

Starts an asynchronous task to move messages from a specified source queue to a specified destination queue.

<note markdown=“1”> * This action is currently limited to supporting message redrive from

queues that are configured as [dead-letter queues (DLQs)][1] of
other Amazon SQS queues only. Non-SQS queue sources of dead-letter
queues, such as Lambda or Amazon SNS topics, are currently not
supported.
  • In dead-letter queues redrive context, the ‘StartMessageMoveTask` the source queue is the DLQ, while the destination queue can be the original source queue (from which the messages were driven to the dead-letter-queue), or a custom destination queue.

  • Only one active message movement task is supported per queue at any given time.

  max_number_of_messages_per_second: 1,
})

Response structure


resp.task_handle #=> String

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :source_arn (required, String)

    The ARN of the queue that contains the messages to be moved to another queue. Currently, only ARNs of dead-letter queues (DLQs) whose sources are other Amazon SQS queues are accepted. DLQs whose sources are non-SQS queues, such as Lambda or Amazon SNS topics, are not currently supported.

  • :destination_arn (String)

    The ARN of the queue that receives the moved messages. You can use this field to specify the destination queue where you would like to redrive messages. If this field is left blank, the messages will be redriven back to their respective original source queues.

  • :max_number_of_messages_per_second (Integer)

    The number of messages to be moved per second (the message movement rate). You can use this field to define a fixed message movement rate. The maximum value for messages per second is 500. If this field is left blank, the system will optimize the rate based on the queue message backlog size, which may vary throughout the duration of the message movement task.

#tag_queue(params = {}) ⇒ Struct

Add cost allocation tags to the specified Amazon SQS queue. For an overview, see [Tagging Your Amazon SQS Queues] in the *Amazon SQS Developer Guide*.

When you use queue tags, keep the following guidelines in mind:

  • Adding more than 50 tags to a queue isn’t recommended.

  • Tags don’t have any semantic meaning. Amazon SQS interprets tags as character strings.

  • Tags are case-sensitive.

  • A new tag with a key identical to that of an existing tag overwrites the existing tag.

For a full list of tag restrictions, see [Quotas related to queues] in the *Amazon SQS Developer Guide*.
