v2.9.15

Changelog

Go Version

• 1.19.6: Both the release executables and Docker images are built with this Go release

Added

• Monitoring
  • Add raft query parameter to /jsz to include group info (#​3915)
  • Update /leafz to include leaf node remove server name and “spoke” flag (#​3923, #​3925)

Changed

• Lower default value of jetstream.max_outstanding_catchup to prevent slow consumers between routes (#​3922)
  • Note: The new value is now 64MB from 128MB. This is better optimized for 1 Gbit links, however if your links are 10 Gbit or higher, this value can be set back to 128MB if slow consumers were not previously observed.

• Refactor intra-process queue to reduce allocations (#​3894)
• JetStream
  • Better system stability and recovery from corrupt metadata due to hard forced restarts (#​3934)
  • Optimize on-disk, per-subject info update (#​3867)
  • Limit concurrent blocking IO to improve stability under heavy IO loads (#​3867)
  • Improve message expiry calculation for large numbers of messages (#​3867)
  • Optimize when and how consumer num pending is calculated, significantly speeding up consumer info requests (#​3877)
  • Improve parallel consumer creation to prevent dropped messages (#​3880)

  • Send current snapshot to followers when becoming meta-leader (#​3904)
  • Ensure preferred peer during stepdown is healthy (#​3905)
  • Optimized various store calls on stream state (#​3910)
  • Various performance and stability under heavy IO loads (#​3922) (Thank you @​matkam and @​davidzhao for the report and the test harness!)

Fixed

• Fix stack overflow panic in reverse entry check when inbox ends with wildcard (#​3862)
• Check if client connection name was already set when storing, preventing recursive memory growth (#​3886)

• Fix panic if service export is nil (#​3917) (Thank you @​MauriceVanVeen for the report!)
• JetStream
  • Ensure per-subject info is updated when doing stream compact (#​3860)
  • Ensure account usage is updated in the filestore when extended version purge occurs (#​3876)
  • Prevent consumer deletes on restart, with non-fatal errors (#​3881)
  • Do not warn if consumer replicas is zero since it will be inherited from the stream (#​3882)
  • Named push consumers with inactive thresholds deleted when still active (#​3884)
  • Prevent spurious “Error storing entry to WAL” log messages (#​3893, #​3891)
  • Clean up consumer redelivery state on stream purge (#​3892)
  • Clean up consumer ack pending if below stream ack floor (#​3892)
  • Update ack floors on messages being expired (#​3892)
  • Fix lost ack pending consumer state on partial stream purge (#​3892)
  • Snapshot and compact the consumer RAFT WAL, even when state changes do not occur, to prevent excessive disk usage (#​3898)
  • Fix KV accounting errors under heavy concurrent usage (#​3900)
  • Ensure new replicas respect MaxAge when a stream is scaled up (#​3861)
  • Snapshots would not compact after being applied (#​3907)
  • Fix filtered pending state calculation (#​3910)
  • Recover from a failed truncate on raft WAL (#​3911)
  • Fix JWT claims update if headers are passed (#​3918)
• MQTT
  • Prevent use of wildcard characters with topics beginning with $, per the MQTT spec violation 4.7.2-1 (#​3926) (Thank you @​dominikh for the report!)
