    Description

      We have 2.0 version but it was happening in version 0.11

      In kafka log there is a lot of messages

      "Received a PartitionLeaderEpoch assignment for an epoch < latestEpoch. This implies messages have arrived out of order."

      On 23.05 we had 

      Received a PartitionLeaderEpoch assignment for an epoch < latestEpoch. This implies messages have arrived out of order. New: {epoch:181, offset:23562380995}, Current: {epoch:362, offset10365488611} for Partition: __consumer_offsets-30 (kafka.server.epoch.LeaderEpochFileCache)

      Currently we have

      Received a PartitionLeaderEpoch assignment for an epoch < latestEpoch. This implies messages have arrived out of order. New: {epoch:199, offset:24588072027}, Current: {epoch:362, offset:10365488611} for Partition: __consumer_offsets-30 (kafka.server.epoch.LeaderEpochFileCache)

      I think kafka should either fix it "under the hood" or have information how to fix it

      There is no information, how dangerous is it and how to fix it
