Bug Fixes

  • Avoid spurious step downs if the append_entries are blocked for longer than usual on the followers. by @bharathv in #19974
  • Don't mark partition rebalance complete if some partitions are not moveable (e.g. due to partial recovery mode) by @ztlpn in #18489
  • Enforce client quota throttling in a Kafka-compatible way, meaning we enforce the throttle delay on the next request if the client did not enforce it on its side. by @pgellert in #18218
  • Fix a bug validating WebAssembly when global constants are specific values that have the encoded byte 0x0B. by @rockwotj in #18077
  • Fix a bug where an invalid buffer passed into the WebAssembly host from the guest could cause Redpanda to abort. by @rockwotj in #18225
  • Fix a scenario where list_offset with a timestamp could return a lower offset than partition start after a trim-prefix command. This could lead to consumers being stuck with an out-of-range-offset exception if they began consuming from an offset below the one which was used in the trim-prefix command. by @nvartolomei in #18112
  • Fix an issue where transforms would miscalculate their initial start offset, leading to consuming the whole input topic. by @oleiman in #20127
  • Fix timequery failing when requested timestamp is in the future and local log is empty. by @nvartolomei in #21312
  • Fix timequery failing with exceptions when the queried partition is empty. by @nvartolomei in #19937
  • Fix transform JavaScript SDK tools on Darwin by @rockwotj in #21490
  • Fixed misnamed schema registry ABI stubs in the Data Transforms Rust SDK and improved tests. by @oleiman in #18555
  • Fixes a bug in the http client where a crash may occur in the event certain tls verification errors are observed by @graphcareful in #18304
  • Fixes a bug that would allow requests to complete that created acls for topics with invalid kafka topic names by @graphcareful in #18701
  • Fixes a bug where remote::list_objects() requests that return truncated results get stuck in an infinite loop by @WillemKauf in #18193
  • Fixes a crash that could happen when reading from local storage with a large number of segments that all do not contain user data. by @andrwng in #18073
  • Fixes compaction related issues of transactional data in groups topic. This prevents a case where groups topic was growing unbounded due to ineffective compaction. by @bharathv in #19931
  • Fixes incorrect ordering of arguments in the cloud cache trim admin endpoint. by @andrwng in #18732
  • Fixes related bugs in which query parameters in remote::list_objects() requests were being improperly assigned to request headers by @WillemKauf in #18193
  • Schema Registry: Improve handling of deleted schema by @BenPope in #19944
  • This fixes a bug in kafka topic configs, where the cleanup.policy config was always set at the topic-level to the cluster default even when the topic creation request did not specify this. by @pgellert in #18284
  • Unbreak building sr-sys crate for wasm32-wasi target by @voutilad in #18307
  • #12920 Fix issuing timequeries to cloud storage if remote.read is not enabled. by @WillemKauf in #17533
  • #13451 Speeds up the shutdown time of partition replicas when compactions are happening. by @andrwng in #21366
  • #15312 Fix an edge case where a timequery returns no results if it races with tiered storage retention and garbage collection. This is important at least for consumers that fall behind retention. They interpret such response as the partition is empty and jump to the HWM instead of resuming consuming from the first available message. by @nvartolomei in #18097
  • #17739 Better mapping of REST error codes by @mmaslankaprv in #18094
  • #18213 Fixes a crash caused by a race between a client disconnect and a segment reader in tiered storage. by @andrwng in #18229
  • #18286 Fixed an assertion triggering in a full-disk scenario by @andijcr in #18303
  • #18415 Fixed a crash during raft snapshot application (prefix truncation of the log). A race condition between raft snapshot application and lagging state machine apply fibers caused the state machine offset to move backwards incorrectly. by @bharathv in #18576
  • #18602 rpk: fixes an error in rpk topic consume that prevented the usage of the --regex flag. by @r-vasquez in #18628
  • concurrent requests of set_log_level + expiration now work as expected by @andijcr in #18397
