When deploying Tungsten Clustering for MySQL / MariaDB / Percona Server, we always recommend an odd number of Manager nodes in each cluster. Let's take a look at how having an odd number of Managers helps keep a Tungsten Cluster functioning and avoids data corruption scenarios (i.e. "split brain").

You already know about the Tungsten Connector which is the "secret sauce" that routes your application database traffic to the appropriate MySQL data source of your cluster. Have you ever wondered how the Connector keeps track of the cluster configuration? How it always knows which host is the master (or masters in a Composite Multimaster topology), and which are slaves?

Enterprises require high availability for their business-critical applications. Even the smallest unplanned outage or even a planned maintenance operation can cause lost sales, productivity, and erode customer confidence. Additionally, updating and retrieving data needs to be robust to keep up with user demand.

One important way to protect your MySQL / MariaDB / Percona Server data is to keep your Tungsten Clustering software up-to-date; but how can you achieve this with zero-downtime?

Learn about the two different methods for installing, updating and upgrading Tungsten Clustering software for MySQL / MariaDB / Percona Server.

We are growing!

Consequently, Continuent needs additional talented staff.

We are currently looking for a person who would be a good fit for our "Database Clustering Technical Sales & Support Engineer" position, in the US Pacific timezone.

Continuent is pleased to announce that Tungsten Clustering 5.3.4 and Tungsten Replicator 5.3.4 are now available!

In this AWS re:Invent talk excerpt, Tyler Turk (Infrastructure Engineer, Riot Games) discusses how the Riot team was able to migrate eight disparate database clusters into AWS as a single composite database cluster replicated in four different AWS regions, provisioned with terraform, and managed and operated by Ansible.

A robust monitoring setup is essential for cluster health and viability - if your replicator goes offline and you do not know about it, then that Replica becomes effectively useless because it has stale data. This means keeping a close watch on the health of the MySQL / MariaDB / Percona Server database nodes from many perspectives, from ensuring sufficient disk space to testing that replication traffic is flowing.

Tungsten Clustering offers a graphical administration tool called the Tungsten Dashboard™ to help with your management burden. The GUI makes the deployment much easier to visualize and administer.

The Tungsten Replicator is an extraordinarily powerful and flexible tool capable of moving vast volumes of data from source to target.

In this blog post we will discuss one specific aspect of the THL (Transaction History Log) - the METADATA unsafe_for_block_commit flag.
