DESCRIPTION

AWS Data Pipeline configures and manages a data-driven workflow called a pipeline. AWS Data Pipeline handles the details of scheduling and ensuring that data dependencies are met so that your application can focus on processing the data.

AWS Data Pipeline provides a JAR implementation of a task runner called AWS Data Pipeline Task Runner. AWS Data Pipeline Task Runner provides logic for common data management scenarios, such as performing database queries and running data analysis using Amazon Elastic MapReduce (Amazon EMR). You can use AWS Data Pipeline Task Runner as your task runner, or you can write your own task runner to provide custom data management.

AWS Data Pipeline implements two main sets of functionality. Use the first set to create a pipeline and define data sources, schedules, dependencies, and the transforms to be performed on the data. Use the second set in your task runner application to receive the next task ready for processing. The logic for performing the task, such as querying the data, running data analysis, or converting the data from one format to another, is contained within the task runner. The task runner performs the task assigned to it by the web service, reporting progress to the web service as it does so. When the task is done, the task runner reports the final success or failure of the task to the web service.

METHODS

ActivatePipeline(PipelineId => Str, [ParameterValues => ArrayRef[Paws::DataPipeline::ParameterValue], StartTimestamp => Str])

Each argument is described in detail in: Paws::DataPipeline::ActivatePipeline

Returns: a Paws::DataPipeline::ActivatePipelineOutput instance

  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.

AddTags(PipelineId => Str, Tags => ArrayRef[Paws::DataPipeline::Tag])

Each argument is described in detail in: Paws::DataPipeline::AddTags

Returns: a Paws::DataPipeline::AddTagsOutput instance

  Adds or modifies tags for the specified pipeline.

CreatePipeline(Name => Str, UniqueId => Str, [Description => Str, Tags => ArrayRef[Paws::DataPipeline::Tag]])

Each argument is described in detail in: Paws::DataPipeline::CreatePipeline

Returns: a Paws::DataPipeline::CreatePipelineOutput instance

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

DeactivatePipeline(PipelineId => Str, [CancelActive => Bool])

Each argument is described in detail in: Paws::DataPipeline::DeactivatePipeline

Returns: a Paws::DataPipeline::DeactivatePipelineOutput instance

  Deactivates the specified running pipeline. The pipeline is set to the
C<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.

DeletePipeline(PipelineId => Str)

Each argument is described in detail in: Paws::DataPipeline::DeletePipeline

Returns: nothing

  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.

DescribeObjects(ObjectIds => ArrayRef[Str], PipelineId => Str, [EvaluateExpressions => Bool, Marker => Str])

Each argument is described in detail in: Paws::DataPipeline::DescribeObjects

Returns: a Paws::DataPipeline::DescribeObjectsOutput instance

  Gets the object definitions for a set of objects associated with the
pipeline. Object definitions are composed of a set of fields that
define the properties of the object.

DescribePipelines(PipelineIds => ArrayRef[Str])

Each argument is described in detail in: Paws::DataPipeline::DescribePipelines

Returns: a Paws::DataPipeline::DescribePipelinesOutput instance

  Retrieves metadata about one or more pipelines. The information
retrieved includes the name of the pipeline, the pipeline identifier,
its current state, and the user account that owns the pipeline. Using
account credentials, you can retrieve metadata about pipelines that you
or your IAM users have created. If you are using an IAM user account,
you can retrieve metadata about only those pipelines for which you have
read permissions.

To retrieve the full pipeline definition instead of metadata about the pipeline, call GetPipelineDefinition.

EvaluateExpression(Expression => Str, ObjectId => Str, PipelineId => Str)

Each argument is described in detail in: Paws::DataPipeline::EvaluateExpression

Returns: a Paws::DataPipeline::EvaluateExpressionOutput instance

  Task runners call C<EvaluateExpression> to evaluate a string in the
context of the specified object. For example, a task runner can
evaluate SQL queries stored in Amazon S3.

GetPipelineDefinition(PipelineId => Str, [Version => Str])

Each argument is described in detail in: Paws::DataPipeline::GetPipelineDefinition

Returns: a Paws::DataPipeline::GetPipelineDefinitionOutput instance

  Gets the definition of the specified pipeline. You can call
C<GetPipelineDefinition> to retrieve the pipeline definition that you
provided using PutPipelineDefinition.

ListPipelines([Marker => Str])

Each argument is described in detail in: Paws::DataPipeline::ListPipelines

Returns: a Paws::DataPipeline::ListPipelinesOutput instance

  Lists the pipeline identifiers for all active pipelines that you have
permission to access.

PollForTask(WorkerGroup => Str, [Hostname => Str, InstanceIdentity => Paws::DataPipeline::InstanceIdentity])

Each argument is described in detail in: Paws::DataPipeline::PollForTask

Returns: a Paws::DataPipeline::PollForTaskOutput instance

  Task runners call C<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 C<workerGroup> parameter. The task returned can
come from any of the pipelines that match the C<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.

PutPipelineDefinition(PipelineId => Str, PipelineObjects => ArrayRef[Paws::DataPipeline::PipelineObject], [ParameterObjects => ArrayRef[Paws::DataPipeline::ParameterObject], ParameterValues => ArrayRef[Paws::DataPipeline::ParameterValue]])

Each argument is described in detail in: Paws::DataPipeline::PutPipelineDefinition

Returns: a Paws::DataPipeline::PutPipelineDefinitionOutput instance

  Adds tasks, schedules, and preconditions to the specified pipeline. You
can use C<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.

QueryObjects(PipelineId => Str, Sphere => Str, [Limit => Int, Marker => Str, Query => Paws::DataPipeline::Query])

Each argument is described in detail in: Paws::DataPipeline::QueryObjects

Returns: a Paws::DataPipeline::QueryObjectsOutput instance

  Queries the specified pipeline for the names of objects that match the
specified set of conditions.

RemoveTags(PipelineId => Str, TagKeys => ArrayRef[Str])

Each argument is described in detail in: Paws::DataPipeline::RemoveTags

Returns: a Paws::DataPipeline::RemoveTagsOutput instance

  Removes existing tags from the specified pipeline.

ReportTaskProgress(TaskId => Str, [Fields => ArrayRef[Paws::DataPipeline::Field]])

Each argument is described in detail in: Paws::DataPipeline::ReportTaskProgress

Returns: a Paws::DataPipeline::ReportTaskProgressOutput instance

  Task runners call C<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 C<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.

ReportTaskRunnerHeartbeat(TaskrunnerId => Str, [Hostname => Str, WorkerGroup => Str])

Each argument is described in detail in: Paws::DataPipeline::ReportTaskRunnerHeartbeat

Returns: a Paws::DataPipeline::ReportTaskRunnerHeartbeatOutput instance

  Task runners call C<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.

SetStatus(ObjectIds => ArrayRef[Str], PipelineId => Str, Status => Str)

Each argument is described in detail in: Paws::DataPipeline::SetStatus

Returns: nothing

  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 C<FINISHED> pipelines and
attempting to do so returns C<InvalidRequestException>.

SetTaskStatus(TaskId => Str, TaskStatus => Str, [ErrorId => Str, ErrorMessage => Str, ErrorStackTrace => Str])

Each argument is described in detail in: Paws::DataPipeline::SetTaskStatus

Returns: a Paws::DataPipeline::SetTaskStatusOutput instance

  Task runners call C<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 C<SetTaskStatus> for
tasks that are canceled by the web service during a call to
ReportTaskProgress.

ValidatePipelineDefinition(PipelineId => Str, PipelineObjects => ArrayRef[Paws::DataPipeline::PipelineObject], [ParameterObjects => ArrayRef[Paws::DataPipeline::ParameterObject], ParameterValues => ArrayRef[Paws::DataPipeline::ParameterValue]])

Each argument is described in detail in: Paws::DataPipeline::ValidatePipelineDefinition

Returns: a Paws::DataPipeline::ValidatePipelineDefinitionOutput instance

  Validates the specified pipeline definition to ensure that it is well
formed and can be run without error.
