1.21. Tungsten Clustering 5.2.1 GA (21 September 2017)

Version End of Life. 31 January 2019

Release 5.2.1 is a bug fix release.

Improvements, new features and functionality

  • Tungsten Connector

    • 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 Clustering for MySQL 5.2 Manual]), or by using multiple localhost entries in (in [Tungsten Clustering for MySQL 5.2 Manual]):

      @hostoption qos=RO_RELAXED

      Any other IP will get the default configuration (generally RW_STRICT (in [Tungsten Clustering for MySQL 5.2 Manual])).

      Issues: CT-341

Bug Fixes

  • Installation and Deployment

    • The tpm connector (in [Tungsten Clustering for MySQL 5.2 Manual]) command would fail to import any local configuration options.

      Issues: CT-137

  • Command-line Tools

    • The tpm connector (in [Tungsten Clustering for MySQL 5.2 Manual]) would fail in MySQL 5.7 deployments because MySQL expects to use SSL by default.

      Issues: CT-363

  • Tungsten Connector

    • A small optimisation has been found in the way the connector reads packets from MySQL.

      Issues: CT-340

    • 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.

      Issues: CT-342

    • When running in bridge mode, the Connecto would not disconnect ongoing connections after losing contact with managers.

      Issues: CT-371

Tungsten Clustering 5.2.1 Includes the following changes made in Tungsten Replicator 5.2.1

Tungsten Replicator 5.2.1 is a minor bugfix release that addresses some bugs found in the previous Tungsten Replicator 5.2.0 GA (19 July 2017) (in [Tungsten Replicator 5.2 Manual]) release. It is a recommended upgrade for all users.
