-- | Updates the AWS Data Pipeline service on the progress of the calling task
-- runner. When the task runner is assigned a task, it should call
-- ReportTaskProgress to acknowledge that it has the task within 2 minutes. If
-- the web service does not recieve this acknowledgement within the 2 minute
-- window, it will assign 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 will assume that the task runner is unable to
-- process the task and will reassign the task in a subsequent response to
-- PollForTask. task runners should call ReportTaskProgress every 60 seconds.
