v23.2.28

Bug Fixes

• Fix a race condition between suffix truncation / delete records and adjacent segment compaction that can lead to crashes and data-loss. by @ nvartolomei in #17254
• Fix initial_leader_epoch/KIP-320 handling in fetch requests. It was ignored until now which prevented consumers to correctly detect suffix truncation. For Redpanda (and Raft), this is a minor problem since suffix truncation is a very improbable event. by @nvartolomei in #17727
• Fixes a bug of config_frontend methods getting called on shards other than the controller shard. by @pgellert in [#17211](https://github.com/ /pull/17211)
• Prevent detecting leader epoch advancement when state is not up to date by @mmaslankaprv in [#17882](https://github.com/redpanda-data/ redpanda/pull/17882)
• Reduces maximum log line size from 1MiB to 128KiB to reduce occurrences of memory allocation failures by @michael-redpanda in #17924
• #16612 fixes small inconsistency between Kafka and Redpanda when trying to query end_offset of an empty log by @mmaslankaprv in #17881
• #17238 Fixes a bug in CreateTopicsResponse to now return all the configs of the topic, not just the topic-specific override configs. by @pgellert in #17241
• #17790 Fix a bug that could lead to raft log inconsistencies when 2 out of 3 nodes in a configuration are changed. by @ztlpn in #17797
• prevents partial consumer group recovery by @mmaslankaprv in #17882
• PR #17160 [v23.2.x] compression: Allocate memory for LZ4_compressEnd by @abhijat
• PR #17826 [v23.2.x] CORE-1722: compression: Use preallocated decompression buffers for lz4 by @abhijat
• PR #17881 [v23.2.x] k/replicated_partition: fixed querying end offset of an empty log by @nvartolomei
• PR #17882 Backport of #17673 #17498 #16560 by @mmaslankaprv

Improvements

• Adds a new public metric redpanda_raft_recovery_partition_movement_consumed_bandwidth that tracks how much bandwidth is currently in use for raft recovery. This helps tune raft_learner_recovery_rate. by @bharathv in #17217

• PR #17397 [v23.2.x] k/group: recover leader epoch on leader change by @nvartolomei * PR #17448 [v23.2.x] tx: fix param ordering in log statement by @nvartolomei

• PR #17577 [v23.2.x] c/topics_frontend: break the loop when dispatching to current leader by @mmaslankaprv
