Overview

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

client = Aws::Keyspaces::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):

  • :plugins (Array<Seahorse::Client::Plugin>) — default: []] —

    A list of plugins to apply to the client. Each plugin is either a class name or an instance of a plugin class.

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials used for authentication. This can be any class that includes and implements ‘Aws::CredentialProvider`, or 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`, `:session_token`, and `:account_id` options.

    • ‘ENV`, `ENV`, `ENV`, and `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::InstanceProfileCredentials` 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)
  • :account_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.

  • :auth_scheme_preference (Array<String>) —

    A list of preferred authentication schemes to use when making a request. Supported values are: ‘sigv4`, `sigv4a`, `httpBearerAuth`, and `noAuth`. When set using `ENV` or in shared config as `auth_scheme_preference`, the value should be a comma-separated list.

    @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.

    • ‘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) —

  • :telemetry_provider (Aws::Telemetry::TelemetryProviderBase) — default: Aws::Telemetry::NoOpTelemetryProvider —

    Allows you to provide a telemetry provider, which is used to emit telemetry data. By default, uses ‘NoOpTelemetryProvider` which will not record or emit any telemetry data. The SDK supports the following telemetry providers:

    • OpenTelemetry (OTel) - To use the OTel provider, install and require the

    ‘opentelemetry-sdk` gem and then, pass in an instance of a `Aws::Telemetry::OTelProvider` for telemetry provider.

  • :token_provider (Aws::TokenProvider) —

    Your Bearer token used for authentication. This can be any class that includes and implements ‘Aws::TokenProvider`, or 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.

  • :validate_params (Boolean) — default: true —

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

  • :endpoint_provider (Aws::Keyspaces::EndpointProvider) —

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

#create_table(params = {}) ⇒ Types::CreateTableResponse

The ‘CreateTable` operation adds a new table to the specified keyspace. Within a keyspace, table names must be unique.

‘CreateTable` is an asynchronous operation. When the request is received, the status of the table is set to `CREATING`. You can monitor the creation status of the new table by using the `GetTable` operation, which returns the current `status` of the table. You can start using a table when the status is `ACTIVE`.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :keyspace_name (required, String) —

    The name of the keyspace that the table is going to be created in.

  • :table_name (required, String) —

    The name of the table.

  • :schema_definition (required, Types::SchemaDefinition) —

    The ‘schemaDefinition` consists of the following parameters.

    For each column to be created:

    • ‘name` - The name of the column.

    • ‘type` - An Amazon Keyspaces data type. For more information, see

  • :capacity_specification (Types::CapacitySpecification) —

    Specifies the read/write throughput capacity mode for the table. The options are:

    • ‘throughputMode:PAY_PER_REQUEST` and

    • ‘throughputMode:PROVISIONED` - Provisioned capacity mode requires `readCapacityUnits` and `writeCapacityUnits` as input.

    The default is ‘throughput_mode:PAY_PER_REQUEST`.

    For more information, see [Read/write capacity modes] in the *Amazon Keyspaces Developer Guide*.

    [1]: docs.aws.amazon.com/keyspaces/latest/devguide/ReadWriteCapacityMode.html

  • :encryption_specification (Types::EncryptionSpecification) —

    Specifies how the encryption key for encryption at rest is managed for the table. You can choose one of the following KMS key (KMS key):

    • ‘type:AWS_OWNED_KMS_KEY` - This key is owned by Amazon Keyspaces.

    • ‘type:CUSTOMER_MANAGED_KMS_KEY` - This key is stored in your account and is created, owned, and managed by you. This option requires the `kms_key_identifier` of the KMS key in Amazon Resource Name (ARN) format as input.

    The default is ‘type:AWS_OWNED_KMS_KEY`.

    For more information, see [Encryption at rest] in the *Amazon Keyspaces Developer Guide*.

    [1]: docs.aws.amazon.com/keyspaces/latest/devguide/EncryptionAtRest.html

  • :point_in_time_recovery (Types::PointInTimeRecovery) —

    Specifies if ‘pointInTimeRecovery` is enabled or disabled for the table. The options are:

    • ‘status=ENABLED`

    • ‘status=DISABLED`

    If it’s not specified, the default is ‘status=DISABLED`.

    For more information, see [Point-in-time recovery] in the *Amazon Keyspaces Developer Guide*.

    [1]: docs.aws.amazon.com/keyspaces/latest/devguide/PointInTimeRecovery.html

  • :ttl (Types::TimeToLive) —

    Enables Time to Live custom settings for the table. The options are:

    • ‘status:enabled`

    • ‘status:disabled`

    The default is ‘status:disabled`. After `ttl` is enabled, you can’t disable it for the table.

    For more information, see [Expiring data by using Amazon Keyspaces Time to Live (TTL)] in the *Amazon Keyspaces Developer Guide*.

    [1]: docs.aws.amazon.com/keyspaces/latest/devguide/TTL.html

  • :default_time_to_live (Integer) —

    The default Time to Live setting in seconds for the table.

    For more information, see [Setting the default TTL value for a table] in the *Amazon Keyspaces Developer Guide*.

    [1]: docs.aws.amazon.com/keyspaces/latest/devguide/TTL-how-it-works.html#ttl-howitworks_default_ttl

  • :tags (Array<Types::Tag>) —

    A list of key-value pair tags to be attached to the resource.

    For more information, see [Adding tags and labels to Amazon Keyspaces resources] in the *Amazon Keyspaces Developer Guide*.

    [1]: docs.aws.amazon.com/keyspaces/latest/devguide/tagging-keyspaces.html

  • :client_side_timestamps (Types::ClientSideTimestamps) —

    Enables client-side timestamps for the table. By default, the setting is disabled. You can enable client-side timestamps with the following option:

    • ‘status: “enabled”`

    ^

    Once client-side timestamps are enabled for a table, this setting cannot be disabled.

  • :auto_scaling_specification (Types::AutoScalingSpecification) —

    The optional auto scaling settings for a table in provisioned capacity mode. Specifies if the service can manage throughput capacity automatically on your behalf.

    Auto scaling helps you provision throughput capacity for variable workloads efficiently by increasing and decreasing your table’s read and write capacity automatically in response to application traffic. For more information, see [Managing throughput capacity automatically with Amazon Keyspaces auto scaling] in the *Amazon Keyspaces Developer Guide*.

    By default, auto scaling is disabled for a table.

    [1]: docs.aws.amazon.com/keyspaces/latest/devguide/autoscaling.html

  • :replica_specifications (Array<Types::ReplicaSpecification>) —

    The optional Amazon Web Services Region specific settings of a multi-Region table. These settings overwrite the general settings of the table for the specified Region.

    For a multi-Region table in provisioned capacity mode, you can configure the table’s read capacity differently for each Region’s replica. The write capacity, however, remains synchronized between all replicas to ensure that there’s enough capacity to replicate writes across all Regions. To define the read capacity for a table replica in a specific Region, you can do so by configuring the following parameters.

    • ‘region`: The Region where these settings are applied. (Required)

    • ‘readCapacityUnits`: The provisioned read capacity units. (Optional)

    • ‘readCapacityAutoScaling`: The read capacity auto scaling settings for the table. (Optional)

  • :cdc_specification (Types::CdcSpecification) —

    The CDC stream settings of the table.

Returns:

Options Hash (params):

  • :keyspace_name (required, String) —

    The name of the keyspace.

  • :type_name (required, String) —

    The name of the user-defined type.

    UDT names must contain 48 characters or less, must begin with an alphabetic character, and can only contain alpha-numeric characters and underscores. Amazon Keyspaces converts upper case characters automatically into lower case characters.

    Alternatively, you can declare a UDT name in double quotes. When declaring a UDT name inside double quotes, Amazon Keyspaces preserves upper casing and allows special characters.

    You can also use double quotes as part of the name when you create the UDT, but you must escape each double quote character with an additional double quote character.

  • :field_definitions (required, Array<Types::FieldDefinition>) —

    The field definitions, consisting of names and types, that define this type.

#delete_table(params = {}) ⇒ Struct

The ‘DeleteTable` operation deletes a table and all of its data. After a `DeleteTable` request is received, the specified table is in the `DELETING` state until Amazon Keyspaces completes the deletion. If the table is in the `ACTIVE` state, you can delete it. If a table is either in the `CREATING` or `UPDATING` states, then Amazon Keyspaces returns a `ResourceInUseException`. If the specified table does not exist, Amazon Keyspaces returns a `ResourceNotFoundException`. If the table is already in the `DELETING` state, no error is returned.

Examples:

Request syntax with placeholder values


resp = client.delete_table({
  keyspace_name: "KeyspaceName", # required

#list_types(params = {}) ⇒ Types::ListTypesResponse

The ‘ListTypes` operation returns a list of types for a specified keyspace.

To read keyspace metadata using ‘ListTypes`, the IAM principal needs `Select` action permissions for the system keyspace. To configure the required permissions, see [Permissions to view a UDT] in the *Amazon Keyspaces Developer Guide*.

#restore_table(params = {}) ⇒ Types::RestoreTableResponse

Restores the table to the specified point in time within the ‘earliest_restorable_timestamp` and the current time. For more information about restore points, see [ Time window for PITR continuous backups] in the *Amazon Keyspaces Developer Guide*.

Any number of users can execute up to 4 concurrent restores (any type of restore) in a given account.

When you restore using point in time recovery, Amazon Keyspaces restores your source table’s schema and data to the state based on the selected timestamp ‘(day:hour:minute:second)` to a new table. The Time to Live (TTL) settings are also restored to the state based on the selected timestamp.

In addition to the table’s schema, data, and TTL settings, ‘RestoreTable` restores the capacity mode, auto scaling settings, encryption settings, and point-in-time recovery settings from the source table. Unlike the table’s schema data and TTL settings, which are restored based on the selected timestamp, these settings are always restored based on the table’s settings as of the current time or when the table was deleted.

You can also overwrite these settings during restore:

  • Read/write capacity mode

  • Provisioned throughput capacity units

  • Auto scaling settings

  • Point-in-time (PITR) settings

  • Tags

For more information, see [PITR restore settings] in the *Amazon Keyspaces Developer Guide*.

Note that the following settings are not restored, and you must configure them manually for the new table:

  • Identity and Access Management (IAM) policies

  • Amazon CloudWatch metrics and alarms

#update_keyspace(params = {}) ⇒ Types::UpdateKeyspaceResponse

Adds a new Amazon Web Services Region to the keyspace. You can add a new Region to a keyspace that is either a single or a multi-Region keyspace. Amazon Keyspaces is going to replicate all tables in the keyspace to the new Region. To successfully replicate all tables to the new Region, they must use client-side timestamps for conflict resolution. To enable client-side timestamps, specify ‘clientSideTimestamps.status = enabled` when invoking the API. For more information about client-side timestamps, see [Client-side timestamps in Amazon Keyspaces] in the *Amazon Keyspaces Developer Guide*.

To add a Region to a keyspace using the ‘UpdateKeyspace` API, the IAM principal needs permissions for the following IAM actions:

  • ‘cassandra:Alter`

  • ‘cassandra:AlterMultiRegionResource`

  • ‘cassandra:Create`

  • ‘cassandra:CreateMultiRegionResource`

  • ‘cassandra:Select`

  • ‘cassandra:SelectMultiRegionResource`

  • ‘cassandra:Modify`

  • ‘cassandra:ModifyMultiRegionResource`

If the keyspace contains a table that is configured in provisioned mode with auto scaling enabled, the following additional IAM actions need to be allowed.

  • ‘application-autoscaling:RegisterScalableTarget`

  • ‘application-autoscaling:DeregisterScalableTarget`

  • ‘application-autoscaling:DescribeScalableTargets`

  • ‘application-autoscaling:PutScalingPolicy`

  • ‘application-autoscaling:DescribeScalingPolicies`

To use the ‘UpdateKeyspace` API, the IAM principal also needs permissions to create a service-linked role with the following elements:

  • ‘iam:CreateServiceLinkedRole` - The action the principal can perform.

  • ‘arn:aws:iam::*:role/aws-service-role/replication.cassandra.amazonaws.com/AWSServiceRoleForKeyspacesReplication`

    • The resource that the action can be performed on.

  • ‘iam:AWSServiceName: replication.cassandra.amazonaws.com` - The only Amazon Web Services service that this role can be attached to is Amazon Keyspaces.

For more information, see [Configure the IAM permissions required to add an Amazon Web Services Region to a keyspace] in the *Amazon Keyspaces Developer Guide*.
