Subject [jira] [Commented] (KAFKA-5217) Improve Streams internal exception handling
Date Tue, 18 Jul 2017 16:34:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-5217?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16091795#comment-16091795

Eno Thereska commented on KAFKA-5217:
-------------------------------------

It wasn't exactly clear what the scope of this JIRA is, as I believe this was created in parallel
with the parent JIRA (and then later converted as a subtask). It's fine to keep it open, as
long as scope is clear.

> Streams does not handle all exceptions gracefully atm, but tend to throw exceptions to
the user, even if we could handle them internally and recover automatically. We want to revisit
this exception handling to be more resilient.
> For example, for any kind of rebalance exception, we should just log it, and rejoin the
consumer group.
