Version End of Life. 31 January 2019
Release 5.2.1 is a bug fix release.
Host-based read-write splitting is now also available in bridge
mode. The solution can work either by using a modified
/etc/hosts (in [Tungsten Replicator 2.1 Manual]), or by using multiple
localhost entries in
user.map (in [Continuent Tungsten 4.0 Manual]):
@hostoption 127.0.0.2 qos=RO_RELAXED
Any other IP will get the default configuration (generally
RW_STRICT (in [Continuent Tungsten 4.0 Manual])).
The tpm connector (in [Continuent Tungsten 4.0 Manual]) command would fail to import any local configuration options.
The tpm connector (in [Continuent Tungsten 4.0 Manual]) would fail in MySQL 5.7 deployments because MySQL expects to use SSL by default.
The logging configuration for the Connector had been badly configured with a check time on the logging file of 30ms in place of desired 30s. This introduced a significant performance deficit due to over-checking the file. This has now been updated to 30s.
Tungsten Replicator 5.2.1 is a minor bugfix release that addresses some bugs found in the previous 5.2.0 in [Tungsten Replicator 5.2 Manual] release. It is a recommended upgrade for all users.
