Improving MySQL Write Performance for Tungsten Cluster Slaves: In this blog post we explore various options for performance tuning MySQL server for better replica replication performance.

Why does the DIY approach fail to deliver vs. the Tungsten Clustering solution for geo-distributed MySQL multimaster deployments? Before we dive into the 10 reasons, note why commercially-supported enterprise software is less risky and in fact less costly.

The power of Tungsten Clustering for MySQL / MariaDB is its built-in intelligent MySQL proxy, known as the Tungsten Connector. The Connector has built-in read-write splitting capabilities, and it is also possible to configure different algorithms which select the appropriate slave (i.e. Round-Robin or Lowest-Latency).

The replicator is a critical piece of the Tungsten Clustering solution for MySQL / MariaDB, as well as its own stand-alone data replication product. Automatic recovery enables the replicator to go back online in the event of a transient failure. In this blog, we discuss how to enable Autorecovery.

Continuent is pleased to announce Tungsten Clustering 5.4.0 and Tungsten Replicator 5.4.0 for MySQL / MariaDB. It's significant in that it introduces MySQL 8 support, along with many new features, stability improvements and bug fixes.

Continuent is pleased to announce Tungsten Clustering 6.1.0 and Tungsten Replicator 6.1.0 for MySQL / MariaDB. It's significant in that it has MySQL 8 support, along with many new features, stability improvements and bug fixes. This release also features a new manager, and it also has the ability to do active/active Composite Multimaster geo-clustering.

How to move the Relay role to another node in a Composite Tungsten Cluster

Part of the power of Tungsten Clustering for MySQL / MariaDB is its intelligent MySQL Proxy, known as the Tungsten Connector. Tungsten Connector has three main modes, and depending on the type of operations you are performing (such as if you need read-write splitting), we help you choose which mode is best. Hence the question, "How can I tell which Tungsten Connector mode I am using: Bridge, Proxy/Direct or Proxy/SmartScale?"

Tungsten Clustering provides high availability, disaster recovery, and a host of other benefits for MySQL / MariaDB / Percona Server databases. In this blog post we will explore some of the shell aliases I use every day to administer various Tungsten Clusters.
