Overview

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

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

For details on configuring region and credentials see the developer guide.

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[:credentials]
    • The :access_key_id, :secret_access_key, and :session_token options.
    • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    • ~/.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.
  • :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:

    • Aws.config[:region]

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

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

  • :retry_backoff (Proc)

    A proc or lambda used for backoff. Defaults to 2**retries * retry_base_delay. This option is only used in the legacy retry mode.

    • 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.

  • :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.

    The number of seconds to wait when opening a HTTP session before raising a Timeout::Error.

  • :http_read_timeout (Integer) — default: 60

    The default number of seconds to wait for response data. 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_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_wire_trace (Boolean) — default: false

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

  • :ssl_verify_peer (Boolean) — default: true

    When true, SSL peer certificates are verified when establishing a connection.

  • :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.

Instance Method Details

#activate_pipeline(params = {}) ⇒ Struct

Validates the specified pipeline and starts processing pipeline tasks. If the pipeline does not pass validation, activation fails.

If you need to pause the pipeline to investigate an issue with a component, such as a data source or script, call DeactivatePipeline.

To activate a finished pipeline, modify the end date for the pipeline and then activate it.

Examples:

Request syntax with placeholder values


resp = client.activate_pipeline({
  pipeline_id: "id", # required
  parameter_values: [
    {
      id: "fieldNameString", # required
      string_value: "fieldStringValue", # required
    },
  ],
  start_timestamp: Time.now,
})

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :pipeline_id (required, String)

    The ID of the pipeline.

  • :parameter_values (Array<Types::ParameterValue>)

    A list of parameter values to pass to the pipeline at activation.

  • :start_timestamp (Time, DateTime, Date, Integer, String)

    The date and time to resume the pipeline. By default, the pipeline resumes from the last completed execution.

Returns:

  • (Struct)

    Returns an empty response.

  req.send_request(options)
end

#add_tags(params = {}) ⇒ Struct

Adds or modifies tags for the specified pipeline.

Examples:

Request syntax with placeholder values


resp = client.add_tags({
  pipeline_id: "id", # required
  tags: [ # required
    {
      key: "tagKey", # required
      value: "tagValue", # required
    },
  ],
})

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :pipeline_id (required, String)

    The ID of the pipeline.

  • :tags (required, Array<Types::Tag>)

    The tags to add, as key/value pairs.

Returns:

  • (Struct)

    Returns an empty response.

end

#create_pipeline(params = {}) ⇒ Types::CreatePipelineOutput

Creates a new, empty pipeline. Use PutPipelineDefinition to populate the pipeline.

Examples:

Request syntax with placeholder values


resp = client.create_pipeline({
  name: "id", # required
  unique_id: "id", # required
  description: "string",
  tags: [
    {
      key: "tagKey", # required
      value: "tagValue", # required
    },
  ],
})

Response structure


resp.pipeline_id #=> String

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :name (required, String)

    The name for the pipeline. You can use the same name for multiple pipelines associated with your AWS account, because AWS Data Pipeline assigns each pipeline a unique pipeline identifier.

  • :unique_id (required, String)

    A unique identifier. This identifier is not the same as the pipeline identifier assigned by AWS Data Pipeline. You are responsible for defining the format and ensuring the uniqueness of this identifier. You use this parameter to ensure idempotency during repeated calls to CreatePipeline. For example, if the first call to CreatePipeline does not succeed, you can pass in the same unique identifier and pipeline name combination on a subsequent call to CreatePipeline. CreatePipeline ensures that if a pipeline already exists with the same name and unique identifier, a new pipeline is not created. Instead, you'll receive the pipeline identifier from the previous attempt. The uniqueness of the name and unique identifier combination is scoped to the AWS account or IAM user credentials.

  • :description (String)

    The description for the pipeline.

  • :tags (Array<Types::Tag>)

    A list of tags to associate with the pipeline at creation. Tags let you control access to pipelines. For more information, see Controlling User Access to Pipelines in the AWS Data Pipeline Developer Guide.

Returns:

end

#deactivate_pipeline(params = {}) ⇒ Struct

Deactivates the specified running pipeline. The pipeline is set to the DEACTIVATING state until the deactivation process completes.

To resume a deactivated pipeline, use ActivatePipeline. By default, the pipeline resumes from the last completed execution. Optionally, you can specify the date and time to resume the pipeline.

Examples:

Request syntax with placeholder values


resp = client.deactivate_pipeline({
  pipeline_id: "id", # required
  cancel_active: false,
})

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :pipeline_id (required, String)

    The ID of the pipeline.

  • :cancel_active (Boolean)

    Indicates whether to cancel any running objects. The default is true, which sets the state of any running objects to CANCELED. If this value is false, the pipeline is deactivated after all running objects finish.

Returns:

  • (Struct)

    Returns an empty response.

end

#delete_pipeline(params = {}) ⇒ Struct

Deletes a pipeline, its pipeline definition, and its run history. AWS Data Pipeline attempts to cancel instances associated with the pipeline that are currently being processed by task runners.

Deleting a pipeline cannot be undone. You cannot query or restore a deleted pipeline. To temporarily pause a pipeline instead of deleting it, call SetStatus with the status set to PAUSE on individual components. Components that are paused by SetStatus can be resumed.

Examples:

Request syntax with placeholder values


resp = client.delete_pipeline({
  pipeline_id: "id", # required
})

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

#poll_for_task(params = {}) ⇒ Types::PollForTaskOutput

Task runners call PollForTask to receive a task to perform from AWS Data Pipeline. The task runner specifies which tasks it can perform by setting a value for the workerGroup parameter. The task returned can come from any of the pipelines that match the workerGroup value passed in by the task runner and that was launched using the IAM user credentials specified by the task runner.

If tasks are ready in the work queue, PollForTask returns a response immediately. If no tasks are available in the queue, PollForTask uses long-polling and holds on to a poll connection for up to a 90 seconds, during which time the first newly scheduled task is handed to the task runner. To accomodate this, set the socket timeout in your task runner to 90 seconds. The task runner should not call PollForTask again on the same workerGroup until it receives a response, and this can take up to 90 seconds.

Examples:

Request syntax with placeholder values


resp = client.poll_for_task({
  worker_group: "string", # required
  hostname: "id",
  instance_identity: {
    document: "string",
    signature: "string",
  },
})

Response structure


resp.task_object.task_id #=> String
resp.task_object.pipeline_id #=> String
resp.task_object.attempt_id #=> String
resp.task_object.objects #=> Hash
resp.task_object.objects["id"].id #=> String

resp.task_object.objects["id"].fields[0].key #=> String
resp.task_object.objects["id"].fields[0].string_value #=> String
resp.task_object.objects["id"].fields[0].ref_value #=> String

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :worker_group (required, String)

    The type of task the task runner is configured to accept and process. The worker group is set as a field on objects in the pipeline when they are created. You can only specify a single value for workerGroup in the call to PollForTask. There are no wildcard values permitted in workerGroup; the string must be an exact, case-sensitive, match.

  • :hostname (String)

    The public DNS name of the calling task runner.

  • :instance_identity (Types::InstanceIdentity)

    Identity information for the EC2 instance that is hosting the task runner. You can get this value from the instance using http://169.254.169.254/latest/meta-data/instance-id. For more information, see Instance Metadata in the Amazon Elastic Compute Cloud User Guide. Passing in this value proves that your task runner is running on an EC2 instance, and ensures the proper AWS Data Pipeline service charges are applied to your pipeline.

Returns:

#put_pipeline_definition(params = {}) ⇒ Types::PutPipelineDefinitionOutput

Adds tasks, schedules, and preconditions to the specified pipeline. You can use PutPipelineDefinition to populate a new pipeline.

PutPipelineDefinition also validates the configuration as it adds it to the pipeline. Changes to the pipeline are saved unless one of the following three validation errors exists in the pipeline.

  1. An object is missing a name or identifier field.
  2. A string or reference field is empty.
  3. The number of objects in the pipeline exceeds the maximum allowed objects.
  4. The pipeline is in a FINISHED state.

Pipeline object definitions are passed to the PutPipelineDefinition action and returned by the GetPipelineDefinition action.

Examples:

#report_task_progress(params = {}) ⇒ Types::ReportTaskProgressOutput

Task runners call ReportTaskProgress when assigned a task to acknowledge that it has the task. If the web service does not receive this acknowledgement within 2 minutes, it assigns the task in a subsequent PollForTask call. After this initial acknowledgement, the task runner only needs to report progress every 15 minutes to maintain its ownership of the task. You can change this reporting time from 15 minutes by specifying a reportProgressTimeout field in your pipeline.

If a task runner does not report its status after 5 minutes, AWS Data Pipeline assumes that the task runner is unable to process the task and reassigns the task in a subsequent response to PollForTask. Task runners should call ReportTaskProgress every 60 seconds.

Examples:

Request syntax with placeholder values


resp = client.report_task_progress({
  task_id: "taskId", # required
  fields: [
    {
      key: "fieldNameString", # required
      string_value: "fieldStringValue",
      ref_value: "fieldNameString",
    },
  ],
})

Response structure


resp.canceled #=> Boolean

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :task_id (required, String)

    The ID of the task assigned to the task runner. This value is provided in the response for PollForTask.

  • :fields (Array<Types::Field>)

    Key-value pairs that define the properties of the ReportTaskProgressInput object.

Returns:

#report_task_runner_heartbeat(params = {}) ⇒ Types::ReportTaskRunnerHeartbeatOutput

Task runners call ReportTaskRunnerHeartbeat every 15 minutes to indicate that they are operational. If the AWS Data Pipeline Task Runner is launched on a resource managed by AWS Data Pipeline, the web service can use this call to detect when the task runner application has failed and restart a new instance.

Examples:

Request syntax with placeholder values


resp = client.report_task_runner_heartbeat({
  taskrunner_id: "id", # required
  worker_group: "string",
  hostname: "id",
})

Response structure


resp.terminate #=> Boolean

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :taskrunner_id (required, String)

    The ID of the task runner. This value should be unique across your AWS account. In the case of AWS Data Pipeline Task Runner launched on a resource managed by AWS Data Pipeline, the web service provides a unique identifier when it launches the application. If you have written a custom task runner, you should assign a unique identifier for the task runner.

  • :worker_group (String)

    The type of task the task runner is configured to accept and process. The worker group is set as a field on objects in the pipeline when they are created. You can only specify a single value for workerGroup. There are no wildcard values permitted in workerGroup; the string must be an exact, case-sensitive, match.

  • :hostname (String)

    The public DNS name of the task runner.

Returns:

end

#set_status(params = {}) ⇒ Struct

Requests that the status of the specified physical or logical pipeline objects be updated in the specified pipeline. This update might not occur immediately, but is eventually consistent. The status that can be set depends on the type of object (for example, DataNode or Activity). You cannot perform this operation on FINISHED pipelines and attempting to do so returns InvalidRequestException.

Examples:

Request syntax with placeholder values


resp = client.set_status({
  pipeline_id: "id", # required
  object_ids: ["id"], # required
  status: "string", # required
})

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :pipeline_id (required, String)

    The ID of the pipeline that contains the objects.

  • :object_ids (required, Array<String>)

    The IDs of the objects. The corresponding objects can be either physical or components, but not a mix of both types.

  • :status (required, String)

    The status to be set on all the objects specified in objectIds. For components, use PAUSE or RESUME. For instances, use TRY_CANCEL, RERUN, or MARK_FINISHED.

Returns:

  • (Struct)

    Returns an empty response.

end

#set_task_status(params = {}) ⇒ Struct

Task runners call SetTaskStatus to notify AWS Data Pipeline that a task is completed and provide information about the final status. A task runner makes this call regardless of whether the task was sucessful. A task runner does not need to call SetTaskStatus for tasks that are canceled by the web service during a call to ReportTaskProgress.

Examples:

Request syntax with placeholder values


resp = client.set_task_status({
  task_id: "taskId", # required
  task_status: "FINISHED", # required, accepts FINISHED, FAILED, FALSE
  error_id: "string",
  error_message: "errorMessage",
  error_stack_trace: "string",
})

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :task_id (required, String)

    The ID of the task assigned to the task runner. This value is provided in the response for PollForTask.

  • :task_status (required, String)

    If FINISHED, the task successfully completed. If FAILED, the task ended unsuccessfully. Preconditions use false.

  • :error_id (String)

    If an error occurred during the task, this value specifies the error code. This value is set on the physical attempt object. It is used to display error information to the user. It should not start with string "Service_" which is reserved by the system.

  • :error_message (String)

    If an error occurred during the task, this value specifies a text description of the error. This value is set on the physical attempt object. It is used to display error information to the user. The web service does not parse this value.

  • :error_stack_trace (String)

    If an error occurred during the task, this value specifies the stack trace associated with the error. This value is set on the physical attempt object. It is used to display error information to the user. The web service does not parse this value.

Returns:

  • (Struct)

    Returns an empty response.
