The following issues are fixed in this release (with an open-source reference, if available):

  • cdc: allow sending writes to the previous generation for some time after switching #7251, #15260. The previous bypass for this issue, retry the request, does not work when using LWT and CDC on the same table. The issue can appear both in CQL CDC and Alternator (Amazon DynamoDB compatible API) Streams.

  • Stability: ScyllaDB locks all memory so we don’t experience high latency due to page faults. However, this only applies from the first time the memory is accessed; the first access can still experience stalls, made larger by using transparent huge pages. #8828.

  • Stability: in rare cases, nodetool getsstables or calling REST API /column_family/sstables/by_key/ can crash the server #17232

  • Stability: query_tombstone_page_limit applies to unpaged queries, while it should not #17241

  • MV Correctness: in some cases, like one base table with many views, updates to MV might be lost. In one example range tombstones made the issue appears earlier #17117

  • Log: schema::describe: print synchronous_updates only when it’s present in extension map #14924

  • Build: Regenerate frozen toolchain for gnutls 3.8.3 and clang clang-16.0.6-4. #17285
