Farooq Qaiser commented on KAFKA-14911: --------------------------------------- My apologies, I only saw this message yesterday, let me see if I can help out with reviews at this point. > Add system tests for rolling upgrade path of KIP-904 > ---------------------------------------------------- > > Key: KAFKA-14911 > URL: https://issues.apache.org/jira/browse/KAFKA-14911 > Project: Kafka > Issue Type: Test > Reporter: Farooq Qaiser > Assignee: Victoria Xia > Priority: Major > Fix For: 3.5.0 > > > As per [~mjsax] comment > [here|https://github.com/apache/kafka/pull/10747#pullrequestreview-1376539752], > we should add a system test to test the rolling upgrade path for > [KIP-904|https://cwiki.apache.org/confluence/x/P5VbDg] which introduces a new > serialization format for groupBy internal repartition topics and was > implemented as part of https://issues.apache.org/jira/browse/KAFKA-12446 > There is `StreamsUpgradeTest.java` and `streams_upgrade_test.py` (cf > `test_rolling_upgrade_with_2_bounces`) as a starting point. > Might be best to do a similar thing as for FK-joins, and add a new test > variation. > The tricky thing about the test would be, to ensure that the repartition > topic is not empty when we do the bounce, so the test should be setup > accordingly. -- This message was sent by Atlassian Jira (v8.20.10#820010)
