ScyllaDB Open Source 4.5.5

The ScyllaDB team announces ScyllaDB Open Source 4.5.5, a bugfix release of the ScyllaDB 4.5 stable branch.

ScyllaDB Open Source 4.5.5, like all past and future 4.x.y releases, is backward compatible and supports rolling upgrades.

Note the latest stable branch is ScyllaDB 4.6 and we recommend upgrading to it.

Once ScyllaDB 5.0 is released, ScyllaDB 4.5 will be retired.

Issues fixed in this release:

  • Stability: compare_atomic_cell_for_merge doesn’t compare TTL if expiry is the same. This is not consistent with the way the cell hash is computed, and may cause  repair to keep trying to repair discrepancies caused by the TTL being different.  #10156, #10173
  • Stability: A crash in ScyllaDB memory management code, triggered by index file caching, was fixed. The bug was caused by an allocation from within the memory allocator causing cache eviction in order to free memory. Freeing the evicted items re-enters the memory allocator, in a way that was not expected by the code. Fixes #9573
  • Stability: JSON formatter issues may cause API calls fail in some cases, for example top partition on a CDC table #9061
  • The INSERT JSON statement now correctly rejects empty string partition keys. #9853
