Features
- Introduces the node config
crash_loop_sleep_sec, which sets the time the broker sleeps before terminating the process when the limit on the number of consecutive times a broker can crash has been reached. This is most useful in Kubernetes environments where setting this value allows customers to have ssh access into a crash looping pod for a short window of time. by @pgellert in #24825
Bug Fixes
- Avoid large allocations for the kafka response sequencing map. by @pgellert in #24743
- Fixes Iceberg metadata serialization to avoid writing an extraneous empty Avro block. This would previously prevent some query engines (e.g. BigQuery) from reading tables created by Iceberg Topics. by @andrwng in #24920
- Fixes a bug where failing to audit an authentication event could lead to a broker crash. by @pgellert in #24738
- Fixes a crash during partition shutdown. This can happen during partition moves (cross core/broker) or at broker shutdown. by @bharathv in #24939
- Fixes an issue where transactions incorrectly timeout due incorrect cleanup of evicted producers. by @bharathv in #24879
- Remove partial kvstore snapshots at startup. by @ztlpn in #24845
- #24914 Fixes integer overflow issues when given a schema via the
POST /subject/{subject}/versionwhere version was > INT_MAX or a negative value was provided. by @michael-redpanda in #24916
