Logging and Tooling Improvements¶
- Added full client info to SHUTDOWN and CLUSTER FAILOVER logs for better traceability of requests. ([#875])
Bug fixes¶
- Resolved issues in replicationSetPrimary where the primary node’s IP/port updates were not correctly handled in the cluster gossip section. (#965)
- Fixed AOF base suffix during rewrites when modifying the aof-use-rdb-preamble setting, ensuring correct suffix caching to prevent inconsistencies. (#886)
- Addressed rare crashes in async IO threads with TLS by preventing concurrent read and write job overlap. (#1011)
- Prevented AOF from being incorrectly disabled after loading RDB data, ensuring proper re-enabling of AOF. (#1001)
- Triggered a save of the cluster configuration file before shutdown to prevent inconsistencies caused by unsaved node configuration changes. (#822)
- Fixed timing issue in CLUSTER SETSLOT to ensure replicas handle migration correctly when receiving the command before the gossip update. (#981)
Performance¶
- Optimized the handling of temporary set objects in SUNION and SDIFF commands, resulting in a 41% performance improvement for SUNION and 27% for SDIFF. (#996)
Behavior Changes¶
- Replicas now flush old data after checking RDB file is valid during disk-based replication, preventing partial data loss and ensuring a clean data load. (#926)
