Scylla Release

Today we are announcing two software maintenance releases for Scylla Open Source:

Scylla 3.0.1

The Scylla team announces the release of Scylla Open Source 3.0.1, a bugfix release of the Scylla Open Source 3.0 stable branch. Scylla Open Source 3.0.1, like all past and future 3.x.y releases, is backward compatible and supports rolling upgrades.

Issues solved in this release:

  • In rare cases on large machines, Scylla may not start. The last log message will be “Completed migration of legacy schema tables”. #4096
  • Using the new Filtering feature in combination with LIMIT applies the limit per page instead of globally. This means a request might get more values in the response than requested #4100

Scylla 2.3.2

The Scylla team announces the release of Scylla Open Source 2.3.2, a bugfix release of the Scylla Open Source 2.3 stable branch. Release 2.3.2, like all past and future 2.3.y releases, is backward compatible and supports rolling upgrades.

Note that the latest stable release of Scylla Open Source is Scylla 3.0 and you are encouraged to upgrade to it.

Issues solved in this release:

  • iotune may report incorrect write bandwidth #4064
  • After a Linux kernel upgrade, Scylla may stop serving requests. This root cause is a bug in the Linux RWF_NOWAIT feature that can cause it to return EIO under some uncertain conditions, even though everything is fine. #3996
  • In extreme out-of-memory situations, failure to allocate an internal data structure used for synchronizing memtable flushes can result in a segmentation fault and crash. #3931
  • In some cases, Scylla streaming failure stop the bootstrap of a new node joining the cluster #3732
  • Wrong values if Size_estimates. Size_estimates is a field in a Scylla system table which holds statistics on table size per node. Tools like Spark are using this field to calculate how large its reads should be #3916
