Github user zhijiangW commented on the issue: https://github.com/apache/flink/pull/4552 @NicoK , thanks for your reviews! I have submitted all the patches you provided offline to address above issues. 1. Remove `FLINK-8425` from this PR. 2. Do you think I should add more tests for `nextBufferIsEvent`? Because I already verified that in previous related tests 3. For adding the switch issue, I found some difficulties to leave messages for you offline. We can further confirm that.
