ASF GitHub Bot commented on KAFKA-5366: --------------------------------------- GitHub user apurvam opened a pull request: https://github.com/apache/kafka/pull/3217 KAFKA-5366: Add concurrent reads to transactions system test This currently fails in multiple ways. One of which is most likely KAFKA-5355, where the concurrent consumer reads duplicates. During broker bounces, the concurrent consumer misses messages completely. This is another bug.
