ACTION 1CHECK 1OTHER 27

성능 개선과 JetStream의 정확성 문제 수정에 초점을 둔 유지보수 릴리스입니다. 비클러스터 환경에 `standalone-server` 제약이 새로 적용되고 Go 도구 모음도 업데이트되었습니다.

조치 필요 (1)

  • breaking소비자 업데이트의 direct 및 sourcing 상태 변경 제한

    소비자 업데이트로 direct 또는 sourcing 상태를 변경할 수 없게 됩니다.

영향 확인 (1)

  • breaking비클러스터 시스템의 복제본 스트림 설정 제한

    replicas를 1보다 크게 설정하고 클러스터형 시스템을 실행하지 않는 경우에 적용됩니다.

    replicas가 1보다 큰 스트림 설정 업데이트는 비클러스터 시스템에서 거부됩니다.

fixes (19)

  • - WebSocket client buffers are recycled more aggressively when reallocating into larger buffers (#8518)
  • - Fixed missing routes after a reconnect when gossiped URLs were rejected (#8527)
  • - The filestore block sync no longer incorrectly skips blocks that were compacted during the same pass (#8456)
  • - The filestore block sync now performs a single directory sync upon completion rather than once per compacted block (#8461)
  • - The filestore I/O semaphore now covers block sync operations (#8462)
  • - Fixed some issues that could prevent stream snapshots from taking place on a clean shutdown (#8465)
  • - The filestore inline compaction no longer ignores sync_interval: always (#8475)
  • - The stream created time is now preserved after recovery on a standalone server (#8471, contributed by @Green7)
  • - Fixed a data race that could apply when accessing the batch ID (#8369)
  • - Fixed a data race when reading the consumer direct or sourcing status (#8478, contributed by @nberlee)
  • - Fixed an issue where the server could fail to distinguish consumer tiers when enforcing limits (#8484)
  • - Fixed a flow control problem where replicated consumers could get stuck after a leader change (#8488)
  • - Fixed various consumer create issues that could destroy the state of an existing consumer with the same name (#8491)
  • - Internal message delete proposals are no longer counted in the JS API statistics (#8502)
  • - Dynamic filestore reservations no longer incorrectly shrink based on used storage after restarts (#8503)
  • - Fixed a signalling issue that could stall Raft catchups (#8501)

  • - Consumer delivery counts will no longer underflow below zero (#8512, contributed by @no-hup)
  • - AckFlowControl consumers from a work queue stream will no longer incorrectly ack messages outside of the consumer filter (#8431, #8528)

value changes (7)

  • - 1.26.7
  • - Removal from service import response maps is now constant-time (#8463)
  • - The client code no longer resets the deadline more times than necessary when flushing client buffers (#8513)
  • - The client write buffers are now freed correctly when the working buffer exceeds a rational size (#8515)
  • - Stream reads are now isolated with a separate lock, which improves the performance of direct gets (#8486)
  • - Improved the performance of looking up matching sequence numbers for multi-subject gets (#8486)
  • - Reduced the number of heap escapes in subject tree matching (#8526)

constraints (1)
