Issue fixed in this release:

  • bloom-filter: default value for components_memory_reclaim_threshold is too strict #18607. Updated from 0.1 to 0.2 in the fix.
  • Stability: chunked_vector::reserve_partial does not work as documented if size > max_chunk_capacity() #19254
  • Stability: node running out of memory and crash during index building and topology change #17476. The root cause is storage_proxy::_throttled_writes may grow without bound #1834
  • Stability: sstable_manager: components reloader fiber should run with maintenance scheduling group #18675
  • MV: ScyllaDB disseminates the materialized view update backlog in order to control update rates. A bug that prevented this in some circumstances was fixed. #18462
