Tungsten Clustering 6.1.1 and Tungsten Replicator 6.1.1 Released

Continuent is pleased to announce that Tungsten Clustering 6.1.1 and Tungsten Replicator 6.1.1 are now available!

Our 6.1.1 release contains both significant improvements and fixes a number of bugs which improve stability in certain parts of the products.

Highlights in the clustering product:

  • Improved how the Manager and Replicator behave when MySQL dies on the master node. This improvement will induce a change of behavior in the product during failover by default, possibly causing a delay in failover as a way to protect data integrity.
  • A new feature called "Cluster State Savepoints" has been implemented.
  • Improved the ability of the Manager to detect un-extracted, desirable binary log events when recovering the old master via cctrl after a failover.
  • Improved the ability to configure the Manager's behavior upon failover.
  • Self-signed security certs now have a 10-year expiration
  • Updated the check_tungsten_services and zabbix_tungsten_services commands to auto-detect active witnesses.
  • If the pipeline source replicator goes OFFLINE, the relay will now reconnect to a different slave.
  • Fixed an issue where the Manager would show an exception when the MySQL check script did not get expected results.
  • Fixed use case where xtrabackup would timeout during backup via cctrl
  • Improve ability to find needed binaries, both locally and over SSH, for command tungsten_find_orphaned

Highlights common to both products:

  • Fixed an issue that would prevent reading remote binary logs when using SSL
  • Restored previously-removed log file symbolic links under $CONTINUENT_ROOT/service_logs/
  • Improve ability to find needed binaries for commands: tungsten_find_position, tungsten_find_seqno and tungsten_get_rtt

Highlights for the replicator product only:

  • Added new property which controls how the THL is extracted in terms of the index gap methodology
  • Added Clickhouse applier support
