Version End of Life. 15 Aug 2024
Release 6.1.22 contains a number of minor bug fixes.
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.
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 :
property=replicator.datasource.global.connectionSpec.usingOptimizedMetadataQuery=true
Issues: CT-2077
