@Generated(value="com.amazonaws:aws-java-sdk-code-generator") public interface DataPipeline
Note: Do not directly implement this interface, new methods are added to it regularly. Extend from
AbstractDataPipeline instead.
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.

@Deprecated void setEndpoint(String endpoint)
AwsClientBuilder#setEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) for
example:
builder.setEndpointConfiguration(new EndpointConfiguration(endpoint, signingRegion));
Callers can pass in just the endpoint (ex: "datapipeline.us-east-1.amazonaws.com") or a full URL, including the
protocol (ex: "datapipeline.us-east-1.amazonaws.com"). If the protocol is not specified here, the default
protocol from this client's ClientConfiguration will be used, which by default is HTTPS.
For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-region-selection.html#region-selection- choose-endpoint
This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
endpoint - The endpoint (ex: "datapipeline.us-east-1.amazonaws.com") or a full URL, including the protocol (ex:
"datapipeline.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate
with.@Deprecated void setRegion(Region region)
AwsClientBuilder#setRegion(String)setEndpoint(String), sets the regional endpoint for this client's service
calls. Callers can use this method to control which AWS region they want to work with.
By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the
ClientConfiguration supplied at construction.
This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions)
for accessing a given region. Must not be null and must be a region where the service is available.Region.getRegion(com.amazonaws.regions.Regions),
Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration),
Region.isServiceSupported(String)ActivatePipelineResult activatePipeline(ActivatePipelineRequest activatePipelineRequest)
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.

account.ListPipelinesResult listPipelines()
listPipelines(ListPipelinesRequest)PollForTaskResult pollForTask(PollForTaskRequest pollForTaskRequest)
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.
pollForTaskRequest - Contains the parameters for PollForTask.InternalServiceErrorException - An internal service error occurred.InvalidRequestException - The request was not valid. Verify that your request was properly formatted, that the signature was
generated with the correct credentials, and that you haven't exceeded any of the service limits for your
account.TaskNotFoundException - The specified task was not found.PutPipelineDefinitionResult putPipelineDefinition(PutPipelineDefinitionRequest putPipelineDefinitionRequest)
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.
Pipeline object definitions are passed to the PutPipelineDefinition action and returned by the
GetPipelineDefinition action.
putPipelineDefinitionRequest - Contains the parameters for PutPipelineDefinition.InternalServiceErrorException - An internal service error occurred.InvalidRequestException - The request was not valid. Verify that your request was properly formatted, that the signature was
generated with the correct credentials, and that you haven't exceeded any of the service limits for your
account.PipelineNotFoundException - The specified pipeline was not found. Verify that you used the correct user and account identifiers.PipelineDeletedException - The specified pipeline has been deleted.QueryObjectsResult queryObjects(QueryObjectsRequest queryObjectsRequest)
Queries the specified pipeline for the names of objects that match the specified set of conditions.
queryObjectsRequest - Contains the parameters for QueryObjects.PipelineNotFoundException - The specified pipeline was not found. Verify that you used the correct user and account identifiers.PipelineDeletedException - The specified pipeline has been deleted.InternalServiceErrorException - An internal service error occurred.InvalidRequestException - The request was not valid. Verify that your request was properly formatted, that the signature was
generated with the correct credentials, and that you haven't exceeded any of the service limits for your
account.RemoveTagsResult removeTags(RemoveTagsRequest removeTagsRequest)
Removes existing tags from the specified pipeline.
removeTagsRequest - Contains the parameters for RemoveTags.InternalServiceErrorException - An internal service error occurred.InvalidRequestException - The request was not valid. Verify that your request was properly formatted, that the signature was
generated with the correct credentials, and that you haven't exceeded any of the service limits for your
account.PipelineNotFoundException - The specified pipeline was not found. Verify that you used the correct user and account identifiers.PipelineDeletedException - The specified pipeline has been deleted.ReportTaskProgressResult reportTaskProgress(ReportTaskProgressRequest reportTaskProgressRequest)
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.
reportTaskProgressRequest - Contains the parameters for ReportTaskProgress.InternalServiceErrorException - An internal service error occurred.InvalidRequestException - The request was not valid. Verify that your request was properly formatted, that the signature was
generated with the correct credentials, and that you haven't exceeded any of the service limits for your
account.TaskNotFoundException - The specified task was not found.PipelineNotFoundException - The specified pipeline was not found. Verify that you used the correct user and account identifiers.PipelineDeletedException - The specified pipeline has been deleted.ReportTaskRunnerHeartbeatResult reportTaskRunnerHeartbeat(ReportTaskRunnerHeartbeatRequest reportTaskRunnerHeartbeatRequest)
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.
reportTaskRunnerHeartbeatRequest - Contains the parameters for ReportTaskRunnerHeartbeat.InternalServiceErrorException - An internal service error occurred.InvalidRequestException - The request was not valid. Verify that your request was properly formatted, that the signature was
generated with the correct credentials, and that you haven't exceeded any of the service limits for your
account.SetStatusResult setStatus(SetStatusRequest setStatusRequest)
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.
setStatusRequest - Contains the parameters for SetStatus.PipelineNotFoundException - The specified pipeline was not found. Verify that you used the correct user and account identifiers.PipelineDeletedException - The specified pipeline has been deleted.InternalServiceErrorException - An internal service error occurred.InvalidRequestException - The request was not valid. Verify that your request was properly formatted, that the signature was
generated with the correct credentials, and that you haven't exceeded any of the service limits for your
account.SetTaskStatusResult setTaskStatus(SetTaskStatusRequest setTaskStatusRequest)
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.
setTaskStatusRequest - Contains the parameters for SetTaskStatus.InternalServiceErrorException - An internal service error occurred.TaskNotFoundException - The specified task was not found.InvalidRequestException - The request was not valid. Verify that your request was properly formatted, that the signature was
generated with the correct credentials, and that you haven't exceeded any of the service limits for your
account.PipelineNotFoundException - The specified pipeline was not found. Verify that you used the correct user and account identifiers.PipelineDeletedException - The specified pipeline has been deleted.ValidatePipelineDefinitionResult validatePipelineDefinition(ValidatePipelineDefinitionRequest validatePipelineDefinitionRequest)
Validates the specified pipeline definition to ensure that it is well formed and can be run without error.
validatePipelineDefinitionRequest - Contains the parameters for ValidatePipelineDefinition.InternalServiceErrorException - An internal service error occurred.InvalidRequestException - The request was not valid. Verify that your request was properly formatted, that the signature was
generated with the correct credentials, and that you haven't exceeded any of the service limits for your
account.PipelineNotFoundException - The specified pipeline was not found. Verify that you used the correct user and account identifiers.PipelineDeletedException - The specified pipeline has been deleted.void shutdown()
ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.
request - The originally executed request.
