/**
* Interface for accessing AWS Data Pipeline asynchronously. Each asynchronous method will return a Java Future object
* representing the asynchronous operation; overloads which accept an {@code AsyncHandler} can be used to receive
* notification when an asynchronous operation completes.
*
*
* 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.
