2015/05/07 - AWS Data Pipeline - 19 new api methods
Adds or modifies tags for the specified pipeline.
Request Syntax
client.add_tags(
pipelineId='string',
tags=[
{
'key': 'string',
'value': 'string'
},
]
)
string
[REQUIRED]
The ID of the pipeline.
list
[REQUIRED]
The tags to add, as key/value pairs.
(dict) --
Tags are key/value pairs defined by a user and associated with a pipeline to control access. AWS Data Pipeline allows you to associate ten tags per pipeline. For more information, see Controlling User Access to Pipelines in the AWS Data Pipeline Developer Guide.
key (string) -- [REQUIRED]
The key name of a tag defined by a user. For more information, see Controlling User Access to Pipelines in the AWS Data Pipeline Developer Guide.
value (string) -- [REQUIRED]
The optional value portion of a tag defined by a user. For more information, see Controlling User Access to Pipelines in the AWS Data Pipeline Developer Guide.
dict
Response Syntax

Creates a new, empty pipeline. Use PutPipelineDefinition to populate the pipeline.
Request Syntax
client.create_pipeline(
name='string',
uniqueId='string',
description='string',
tags=[
{
'key': 'string',
'value': 'string'
},
]
)
string
[REQUIRED]
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.
string
[REQUIRED]
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.
string
The description for the pipeline.
list
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.

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.

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.
Request Syntax
client.set_status(
pipelineId='string',
objectIds=[
'string',
],
status='string'
)
string
[REQUIRED]
The ID of the pipeline that contains the objects.

[REQUIRED]
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.
None
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.
Request Syntax
client.delete_pipeline(
pipelineId='string'
)
string
[REQUIRED]
The ID of the pipeline.
None
Task runners call 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.

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.
Request Syntax

fields=[
{
'key': 'string',
'stringValue': 'string',
'refValue': 'string'
},

}
Response Structure
(dict) --
Contains the output of ReportTaskProgress.
canceled (boolean) --
If true, the calling task runner should cancel processing of the task. The task runner does not need to call SetTaskStatus for canceled tasks.
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.

Defines a validation warning. Validation warnings do not prevent pipeline activation. The set of validation warnings that can be returned are defined by AWS Data Pipeline.
id (string) --
The identifier of the object that contains the validation warning.
warnings (list) --
A description of the validation warning.
(string) --
errored (boolean) --
Indicates whether there were validation errors.
Lists the pipeline identifiers for all active pipelines that you have permission to access.
Request Syntax
client.list_pipelines(
marker='string'
)
string
The starting point for the results to be returned. For the first call, this value should be empty. As long as there are more results, continue to call ListPipelines with the marker value from the previous call to retrieve the next set of results.

}
Response Structure
(dict) --
Contains the output of ListPipelines.
pipelineIdList (list) --
The pipeline identifiers. If you require additional information about the pipelines, you can use these identifiers to call DescribePipelines and GetPipelineDefinition.
(dict) --
Contains the name and identifier of a pipeline.
id (string) --
The ID of the pipeline that was assigned by AWS Data Pipeline. This is a string of the form df-297EG78HU43EEXAMPLE.
name (string) --
The name of the pipeline.
marker (string) --
The starting point for the next page of results. To view the next page of results, call ListPipelinesOutput again with this marker value. If the value is null, there are no more results.
hasMoreResults (boolean) --
Indicates whether there are more results that can be obtained by a subsequent call.
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.
Request Syntax
client.poll_for_task(
workerGroup='string',
hostname='string',
instanceIdentity={
'document': 'string',
'signature': 'string'
}
)
string
[REQUIRED]
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.
string
The public DNS name of the calling task runner.
dict
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.
document (string) --
A description of an EC2 instance that is generated when the instance is launched and exposed to the instance via the instance metadata service in the form of a JSON representation of an object.
signature (string) --
A signature which can be used to verify the accuracy and authenticity of the information provided in the instance identity document.

Response Structure
(dict) --
Contains the output of PollForTask.
taskObject (dict) --
The information needed to complete the task that is being assigned to the task runner. One of the fields returned in this object is taskId, which contains an identifier for the task being assigned. The calling task runner uses taskId in subsequent calls to ReportTaskProgress and SetTaskStatus.
taskId (string) --
An internal identifier for the task. This ID is passed to the SetTaskStatus and ReportTaskProgress actions.
pipelineId (string) --
The ID of the pipeline that provided the task.
attemptId (string) --
The ID of the pipeline task attempt object. AWS Data Pipeline uses this value to track how many times a task is attempted.
objects (dict) --
Connection information for the location where the task runner will publish the output of the task.
(string) --
(dict) --
Contains information about a pipeline object. This can be a logical, physical, or physical attempt pipeline object. The complete set of components of a pipeline defines the pipeline.
id (string) --
The ID of the object.
name (string) --
The name of the object.
fields (list) --
Key-value pairs that define the properties of the object.
(dict) --
A key-value pair that describes a property of a pipeline object. The value is specified as either a string value ( StringValue) or a reference to another object ( RefValue) but not as both.
key (string) --
The field identifier.
stringValue (string) --
The field value, expressed as a String.
refValue (string) --
The field value, expressed as the identifier of another object.
