bbejeck opened a new pull request, #22526:
URL: https://github.com/apache/kafka/pull/22526
Docs-only change documenting the KIP-1035 RocksDB flush behavior in 4.3: the
changelog offset is now durable only on an organic memtable flush
(write_buffer_size) or clean close (no more per-commit
force-flush), so a low-traffic store + unclean exit can leave a stale
offset that surfaces as `OffsetOutOfRangeException/TaskCorruptedException` on
restart. Extends the upgrade guide's KIP-1035 entry
(incl. a note that 4.3.0's contributing defects are fixed in 4.3.1,
KAFKA-20663) and adds a "Changelog offset durability and flush frequency"
subsection to the RocksDB memory-management guide with
write_buffer_size tuning and clean-shutdown guidance.
No code or public API changes.
