Reviewer: Gwen Shapira
Status: Patch Available (was: Open)
> Allow copycat sink tasks to pause/resume consumption of specific topic
> partitions
> ---------------------------------------------------------------------------------
>
> Key: KAFKA-2482
> URL: https://issues.apache.org/jira/browse/KAFKA-2482
> Project: Kafka
> Issue Type: Sub-task
> Components: copycat
> Reporter: Ewen Cheslack-Postava
> Assignee: Ewen Cheslack-Postava
> Fix For: 0.9.0.0
>
>
> Consider a situation where a sink is assigned 2 topic partitions. One of them
> runs into a transient issue and no more data from it can be processed.
> However, the other topic partition is proceeding fine. We don't want to block
> the second partition by constantly throwing exceptions due to data from the
> first topic partition.
> The new consumer now supports pause/resume, so we should expose these to the
> task. We could expose the functionality directly, although that would also
> make the task responsible for scheduling some task in the future to check
> whether it can resume. Another approach might be to make the API include the
> backoff time. Then the framework would automatically resume consumption of
> the topic partition after that time, which would presumably prompt the task
> to reevaluate the situation for the topic partition when it receives another
> message for it.
