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 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
