2.9. Tungsten Replicator 6.1.22 GA (6 July 2023)

Version End of Life. 15 Aug 2024

Release 6.1.22 contains a number of minor bug fixes.

Bug Fixes

  • Installation and Deployment

    • Fixed RPM package script to run tpm install instead of tpm update when installing the rpm

      Issues: CT-2130

  • PostgreSQL Applier

    • Fixed a NullPointerException error occurring at startup when applying to PostgreSQL

      Issues: CT-2021

  • Core Replicator

    • A change in the way MySQL logs CREATE TABLE AS SELECT in the Binary Logs from v8.0.20 onwards, meant these transactions would previously fail.


      Whilst these statements will now replicate, it mut be noted that in the event of a failure during the data load, the initial CREATE statement won't be rolled back, and therefore care must be taken when using this type of DDL.


      This only affects customers using MySQL v8.0.20+ running with ROW based replication. An alternative workaround to ensure correct rollback on failure, would be to run the statement with STATEMENT based replication for the session. This will also provide better performance for larger tables.

      Issues: CT-1301

    • Fixed an issue where an extracted JSON field could be invalid, with doubled commas in JSON arrays.

      Issues: CT-2049

    • Improved a query that is run by Tungsten when fetching tables metadata (column names, datatypes, etc). While it is not generally needed, the unoptimized query can run badly (especially) against old mysql versions with a lot of databases / tables. For now, the new optimized query is not used by default, but this could change in some future version.

      This can be enabled by using the following property :
