Functionality improvements for Tungsten Manager

Tungsten Package Manager (tpm) fixes

The Tungsten Package Manager (tpm), is a complete configuration, installation and deployment tool for Tungsten Clustering and Tungsten Replicator, which includes some utility commands to simplify those and other processes. Release 6.1.4 contains a range of improvements and bug fixes for the tpm command line tool, the list of which customers can find in the release notes.

Full support for MySQL 8.0.20 binlog compression feature

Tungsten Replicator can now correctly extract and parse Binary Log entries when the MySQL option binlog-transaction-compression (a new parameter introduced from MySQL 8.0.20) has been enabled.

Daylight Saving / Time zone fixes

When host server time (and thus MySQL time) is not configured as UTC, issuing cluster heartbeat or trepctl heartbeat in the first hour of daylight savings time would create an invalid time in MySQL.

Drizzle Driver improvements

The drizzle driver included with both Tungsten Clustering and Tungsten Replicator is used for communications to the MySQL database from the various Tungsten components. In this release a number of changes have been implemented within the driver to improve performance of reads and writes.

Command line tool fixes

tungsten_provision_slave script

The tungsten_provision_slave script allows customers to easily provision, or reprovision, a database server using information from a remote host. In this release the tungsten_provision_slave script has been rewritten and totally replaced. This new version was available in previous releases as a Beta script (prov-sl.sh)

Amazon AWS SSL Certificates support

Tungsten Replicator now recognises Amazon AWS SSL Certificates to enable SSL communication with AWS Aurora. Users can trial Tungsten Replicator on the Amazon Marketplace here.

Improvements for Redshift applier

A number of improvements have been made to the Redshift Applier including better handling of table level locking, specifically with multiple appliers and/or in high data volume environments. These improvements reduce the risk of Redshift serializable isolation violation errors.

New dropRow and delayinMS filters

A new droprow JavaScript filter has been added, which works at ROW level and allows the filtering out of rows based on one or more column/value matches.

A new delayInMs filter has also been added which allows the applying of THL to a slave to be delayed by a period specified in milliseconds. This filter works in the same way as the TimeDelayFilter, however that filter only allows second precision.
