Preface: Currently when the sweeper processes a workflow and the task is in progress the sweeper picks up the task response timeout and queues a message on the decider queue using this time to calculate when to next process the workflow. On occasion when the sweeper and task completion events happen out of order this can have the effect of leaving workflows with completed tasks in limbo for long periods. With their tasks not being scheduled until that timeout is reached.
This fix pr addresses this by adding a config value MaxPostponeDurationSeconds to allow for tasks that may have a long and varied response time to be processed by the sweeper on a minimum schedule.
Describe alternative implementation you have considered
I have looked at ways to push the workflow to the decider but due to the asynchronous nature this can on occasion still fall out of step.
