A.2. Tungsten Clustering 6.1.10 GA (15 Dec 2020)

Version End of Life. Not Yet Set

Release 6.1.10 is a critical bug fix addressing an issue with Parallel Apply within a clustered environemnt.

Improvements, new features and functionality

  • Command-line Tools

    • tpm diag now collects routing table information via route -n , and has two new command-line arguments: --include and --groups.

      --include specifies a comma-separated list of subroutines to include. Any gather subroutine not listed will be skipped.

      --groups specifies a comma-separated list of subroutine groups to include. Any group not listed will be skipped.

      Issues: CT-1399

  • Filters

    • A number of sql_modes have been removed in MySQL 8.0, meaning that when replicating from an earlier version (e.g. 5.7) the applier could error when applying session variables.

      A new sqlmodes filter is now available that should be configured against appliers where the source is version 5.7 or earlier and the target is version 8.0 or later.

      Issues: CT-1361

Bug Fixes

  • Tungsten Manager

    • If parallel apply has been enabled, automatic failovers could hang indefinetly if one of more channels are inactive.

      Important

      All customer using parallel apply are urged to apply this release to avoid production outages due to this known issue.
