Constructor Details

#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::InstanceProfileCredentials` - Used for loading credentials from an EC2 IMDS on an EC2 instance.

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

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

    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 IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of ‘Aws::InstanceProfileCredentails` to enable retries and extended timeouts.

  • :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 search 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`.

  • :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_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.

  • :disable_host_prefix_injection (Boolean) — default: false —

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

  • :endpoint (String) —

    The client endpoint is normally constructed from the ‘:region` option. You should only configure an `:endpoint` when connecting to test endpoints. This should be avalid HTTP(S) URI.

  • :endpoint_cache_max_entries (Integer) — default: 1000 —

    Used for the maximum size limit of the LRU cache storing endpoints data for endpoint discovery enabled operations. Defaults to 1000.

  • :endpoint_cache_max_threads (Integer) — default: 10 —

    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. Defaults to `false`.

  • :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.

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

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

  • :retry_base_delay (Float) — default: 0.3 —

    The base delay in seconds used by the default backoff function.

  • :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.

    @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 and auth errors from expired credentials.

  • :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.

  • :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.

  • :validate_params (Boolean) — default: true —

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

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :cluster_name (required, String) —

    The cluster identifier. This parameter is stored as a lowercase string.

    Constraints:

    • A name must contain from 1 to 20 alphanumeric characters or hyphens.

    • The first character must be a letter.

    • A name cannot end with a hyphen or contain two consecutive hyphens.

  • :node_type (required, String) —

    The compute and memory capacity of the nodes in the cluster.

  • :description (String) —

    A description of the cluster.

  • :replication_factor (required, Integer) —

    The number of nodes in the DAX cluster. A replication factor of 1 will create a single-node cluster, without any read replicas. For additional fault tolerance, you can create a multiple node cluster with one or more read replicas. To do this, set ReplicationFactor to 2 or more.

    <note markdown=“1”> AWS recommends that you have at least two read replicas per cluster.

    </note>
  • :availability_zones (Array<String>) —

    The Availability Zones (AZs) in which the cluster nodes will be created. All nodes belonging to the cluster are placed in these Availability Zones. Use this parameter if you want to distribute the nodes across multiple AZs.

  • :subnet_group_name (String) —

    The name of the subnet group to be used for the replication group.

    DAX clusters can only run in an Amazon VPC environment. All of the subnets that you specify in a subnet group must exist in the same VPC.

  • :security_group_ids (Array<String>) —

    A list of security group IDs to be assigned to each node in the DAX cluster. (Each of the security group ID is system-generated.)

    If this parameter is not specified, DAX assigns the default VPC security group to each node.

  • :preferred_maintenance_window (String) —

    Specifies the weekly time range during which maintenance on the DAX cluster is performed. It is specified as a range in the format ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance window is a 60 minute period. Valid values for ‘ddd` are:

    • ‘sun`

    • ‘mon`

    • ‘tue`

    • ‘wed`

    • ‘thu`

    • ‘fri`

    • ‘sat`

    Example: ‘sun:05:00-sun:09:00`

    <note markdown=“1”> If you don’t specify a preferred maintenance window when you create or modify a cache cluster, DAX assigns a 60-minute maintenance window on a randomly selected day of the week.

    </note>
  • :notification_topic_arn (String) —

    The Amazon Resource Name (ARN) of the Amazon SNS topic to which notifications will be sent.

    <note markdown=“1”> The Amazon SNS topic owner must be same as the DAX cluster owner.

    </note>
  • :iam_role_arn (required, String) —

    A valid Amazon Resource Name (ARN) that identifies an IAM role. At runtime, DAX will assume this role and use the role’s permissions to access DynamoDB on your behalf.

  • :parameter_group_name (String) —

    The parameter group to be associated with the DAX cluster.

  • :tags (Array<Types::Tag>) —

    A set of tags to associate with the DAX cluster.

  • :sse_specification (Types::SSESpecification) —

    Represents the settings used to enable server-side encryption on the cluster.

Returns:

#describe_clusters(params = {}) ⇒ Types::DescribeClustersResponse

Returns information about all provisioned DAX clusters if no cluster identifier is specified, or about a specific DAX cluster if a cluster identifier is supplied.

If the cluster is in the CREATING state, only cluster level information will be displayed until all of the nodes are successfully provisioned.

If the cluster is in the DELETING state, only cluster level information will be displayed.

If nodes are currently being added to the DAX cluster, node endpoint information and creation time for the additional nodes will not be displayed until they are completely provisioned. When the DAX cluster state is available, the cluster is ready for use.

If nodes are currently being removed from the DAX cluster, no endpoint information for the removed nodes is displayed.
