ProxySQL Native Support for Percona XtraDB Cluster (PXC)

ProxySQL in its versions up to 1.x did not natively support Percona XtraDB Cluster (PXC). Instead, it relied on the flexibility offered by the scheduler. This approach allowed users to implement their own preferred way to manage the ProxySQL behaviour in relation to the Galera events.

From version 2.0 we can use native ProxySQL support for PXC.. The mechanism to activate native support is very similar to the one already in place for group replication.

In brief it is based on the table [runtime_]mysql_galera_hostgroups and the information needed is mostly the same:

  • writer_hostgroup: the hostgroup ID that refers to the WRITER

Tungsten Clustering 5.3.6 and Tungsten Replicator 5.3.6 Released

Continuent is pleased to announce that Tungsten Clustering 5.3.6 and Tungsten Replicator 5.3.6 are now available!

Our 5.3.6 release fixes a number of bugs and has been released to improve stability.

Highlights common to both products:

  • Now, instead of searching for a master with appropriate role (i.e. matching the slave preferred role) until timeout is reached, the replicator will loop twice before accepting connection to any host no matter what its role is. (CT-712)
  • Changing the state machine so that RESTORING is not a substate of OFFLINE:NORMAL, but instead of OFFLINE so that a transition from OFFLINE:NORMAL:RESTORING to ONLINE is not possible any longer. Now it will not be possible to transition from
    OFFLINE:RESTORING to ONLINE (CT-797)
  • When an heartbeat is inserted, it will now use the JVM timezone instead of hardcoded UTC. (CT-803)
  • Now skipping files that are not …

Tungsten Clustering 6.0.4 and Tungsten Replicator 6.0.4 Released

Continuent is pleased to announce that Tungsten Clustering 6.0.4 and Tungsten Replicator 6.0.4 are now available!

Our v6.0.4 release fixes a number of bugs and introduces some new features, with improvements across the board in a variety of different components.

Some of the key improvements include:

  • When installing from an RPM, the installation would automatically restart the Connector during the installation. This behavior can now be controlled by setting the parameter --no-connectors within the configuration to prevent tpm from restarting the Connectors during the automated update processing.
  • Cross-site Replicators within a composite multimaster deployment can now be configured to point to slaves by default, and to prefer slaves over masters during operation using the new --policy-relay-from-slave=true option
  • You can now enable an option so …
