PollForTaskto receive a task to perform from AWS Data Pipeline. The task runner specifies which tasks it can perform by setting a value for the
workerGroupparameter. The task returned can come from any of the pipelines that match the
workerGroupvalue 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,
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
PollForTask again on the same
workerGroup until it
receives a response, and this can take up to 90 seconds.
