Real time database replication is a must for clustering and other key business purposes, like reporting. There are a number of replication technologies available for MySQL, and some are even bundled into various solutions. When choosing a replication methodology, it is paramount to understand just how the data moves from source to target. In this blog post, we will examine how asynchronous, synchronous, and "semi-synchronous" replication behave when used for clustering. Also, we will explore how replication affects database performance and data availability.

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 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.

In this blog post we discuss importing CSV data into a Tungsten Cluster.

Overview The Skinny

From time to time we are asked how to check whether or not there are data discrepancies between Master/Slave nodes within a MySQL (or MariaDB) cluster that's managed with Tungsten Clustering.

Continuent is pleased to announce that Tungsten Clustering 6.0.5 and Tungsten Replicator 6.0.5 are now available!

Our v6.0.5 release fixes a number of bugs and introduces some new features, with improvements across the board in a variety of different components.
