Release Notes for August 14, 2019

Bug fixes

  • Fixed a bug that could lead to data inconsistencies and crashes with the message consistency check failed with N inconsistent replicas. #40353
  • Fixed incorrect results, or "unordered span" errors, in some cases involving exclusive inequalities with non-numeric types. #38897
  • Fixed a potential infinite loop in queries involving reverse scans. #39105
  • Unary negatives in constant arithmetic expressions are no longer ignored. #39368
  • Fix wrong comparator used in RocksDB compaction picker, which can lead to infinite compaction loop. #40752
  • Fix bug where MVCC value at future timestamp is returned after a transaction restart. #40632
  • Consider intents in a read's uncertainty interval to be uncertain just as if they were committed values. This removes the potential for stale reads when a causally dependent transaction runs into the not-yet resolved intents from a causal ancestor. #40632
