This post covers some standard Nagios checks that would help keep your Tungsten cluster nodes running MySQL / MariaDB / Percona Server healthy.

In this blog post we explore various options for performance tuning MySQL server for better replica replication performance.

In this blog post we will define what a split-brain scenario means in a MySQL database cluster, and then explore how a Tungsten MySQL database cluster reacts to a split-brain situation.

The Question

Recently, a customer asked us:

Why would heavy disk IO cause the Tungsten Manager and not MySQL to be starved of resources?

For example, we saw the following in the Manager log file tmsvc.log:

AWS may reboot your Aurora database. What is the impact?

Beyond uptime lies the calm harbor of long-term administration for your MySQL high-availability solution. But navigating upgrade waves and vendor lock-in can be tricky. Let's chart a smooth course through these challenges and ensure your data sails serenely.

This article will explain how to use rsync to quickly provision a database.

In this blog, we cover Continuents plans on the support model for the new MySQL “Innovation” releases.

If you are upgrading from MySQL 5.x to MySQL 8, using Tungsten Clustering or Tungsten Replicator, then you may need to prepare yourself for a little gotcha.

One nice thing about Tungsten Clustering is that you need just a single command to move the primary role to another host in your cluster.

Tungsten clustering supports a variety of topologies, each with unique characteristics. Today we introduce yet another compelling topology for your consideration: Tungsten Distributed Datasource Groups, with the new ability to failover automatically between Regions or Datacenters.
