Jun Rao resolved KAFKA-7557. ---------------------------- Resolution: Fixed Fix Version/s: 2.2.0 merged to trunk > optimize LogManager.truncateFullyAndStartAt() > --------------------------------------------- > > Key: KAFKA-7557 > URL: https://issues.apache.org/jira/browse/KAFKA-7557 > Project: Kafka > Issue Type: Bug > Affects Versions: 2.0.0, 2.1.0 > Reporter: Jun Rao > Assignee: huxihx > Priority: Major > Fix For: 2.2.0 > > > When a ReplicaFetcherThread calls LogManager.truncateFullyAndStartAt() for a > partition, we call LogManager.checkpointLogRecoveryOffsetsInDir() and then > Log.deleteSnapshotsAfterRecoveryPointCheckpoint() on all the logs in that > directory. This requires listing all the files in each log dir to figure out > the snapshot files. If some logs have many log segment files. This could take > some time. The can potentially block a replica fetcher thread, which > indirectly causes the request handler threads to be blocked. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
