However, when the time comes to perform the switch action, all of the calling clients have been funneled through the proxy, so identification of the calling host from the database itself becomes difficult.

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

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.

Where are the logs for a Tungsten Cluster and which are the proper log files to monitor if I do a master role switch to another node?

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

Great SaaS - starts with great software. But not enough is said about the people and values behind great software; so that’s what I want to talk about here.

This is the first in a series of blog articles that will discuss the changing landscape of open source and money. Or more specifically open source databases and money.

Latency-sensitive applications running in Java sometimes experience unacceptable delays under heavy I/O load. This blog discusses why this problem occurs and what to do about it for applications running Tungsten Clustering for MySQL.

This blog explains data replication and clustering in a way that anybody can understand.

We were pleased to sponsor the Percona Live Conference in Austin this year: many thanks to the Percona Team for organising a smooth conference yet again!

This is the recap of our week in Texas!

When it comes to zero downtime, proxies are the first line components of a cluster. In order to achieve High Availability (HA) for MySQL, MariaDB and Percona Server, a commonly deployed setup consists of configuring load balancers (hardware or software) on top of those proxies.
