Clustering

A short contemplation about the current state of the programming languages. What language to choose for a new project? What are the differences between them? Is there a best language for everything?

This post shares the links to three short demo videos, each an easy-to-follow walk-through of how to launch 3-node single, active/passive or active/active Tungsten MySQL clusters using AWS CloudFormation.

Read this blog to get a more in-depth understanding of what the Tungsten Cluster AMI is, how it works and how to use it in order to easily deploy MySQL database clusters and more.

This blog discusses Asynchronous versus Synchronous MySQL replication for MySQL clustering. Synchronous replication is viewed as the ‘holy grail’ of clustering. But unfortunately, when something is too good to be true, it often is. Before the Tungsten cluster solution Continuent built two synchronous replication cluster solutions (m/cluster, uni/cluster), but we abandoned those for good reasons.

What is the difference between MySQL replication and MySQL clustering? While clustering involves a layer of replication, the capabilities, benefits, and reasons for using clustering versus replication are very different. At Continuent, we offer both clustering and replication for your MySQL, MariaDB, and Percona MySQL - in the cloud, on-prem, hybrid-cloud and multi-cloud, with no application changes or downtime necessary.

This blog explores the best practices for deploying Tungsten Clustering for MySQL across Availability Zones, outlining the approaches for best high availability, fast response times, and load balancing recommendations.

Version 6+ of Tungsten Clustering comes with a host of improvements for your Multi-Site Multi-Master topology (MSMM); this is partly why it has a new name: Composite Master-Master (CMM). Probably the most notable improvement is that the Managers are more aware. What does that mean?

The Tungsten Connector is an intelligent MySQL proxy that provides key high-availability and read-scaling features. This includes the ability to route MySQL queries by inspecting them in-flight.

Continuent is pleased to announce that Tungsten Clustering 6.1.1 and Tungsten Replicator 6.1.1 are now available! Our 6.1.1 release contains both significant improvements and fixes a number of bugs which improve stability in certain parts of the products.

Continuent is pleased to announce that Tungsten Clustering 5.4.1 and Tungsten Replicator 5.4.1 are now available! Our 5.4.1 release contains both significant improvements and fixes a number of bugs which improve stability in certain parts of the products.

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.
