Container for the parameters to the PollForTask operation.
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.
