---------------------------------------
bbejeck opened a new pull request #4511: KAFKA-6364: second check for ensuring
changelog topic not changed during restore
URL: https://github.com/apache/kafka/pull/4511
Added a second check for race condition where store changelog topic updated
during restore, but not if a KTable changelog topic.
This will be tricky to test, but I wanted to push the PR to get feedback on
the approach.
