Database Proxies provide a single entry point into MySQL for the calling client applications. Proxies are wonderful tools to handle various situations like a master role switch to another node for maintenance, or for transparency with read and write connections. 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

Part of the power of Tungsten Clustering for MySQL / MariaDB is its intelligent MySQL Proxy, known as the Tungsten Connector. Tungsten Connector has three main modes, and depending on the type of operations you are performing (such as if you need read-write splitting), we help you choose which mode is best. Hence the question, "How can I tell which Tungsten Connector mode I am using: Bridge, Proxy/Direct or Proxy/SmartScale?"

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.

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.

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.

This blog is about configuring Tungsten for PCI compliance.

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.

In this blog post we will discuss how to use the Tungsten Connector keep-alive feature to ensure long-running MySQL & MariaDB/Percona Server client sessions stay connected in a Tungsten Cluster.

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.
