[jira] [Commented] (KAFKA-6256) Flaky Unit test:
KStreamKTableJoinIntegrationTest.shouldCountClicksPerRegionWithNonZeroByteCache
[ https://issues.apache.org/jira/browse/KAFKA-6256?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16304637#comment-16304637 ]
Narendra Kumar commented on KAFKA-6256:
---------------------------------------
I doubt this has something to do with commit.interval.ms, the cache might be getting flushed in between resulting partially aggregated records in output topic. [~mjsax] what do you think, any pointers on this?
