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.

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. And even more specifically MySQL and its all variants (AWS Aurora, MariaDB, Percona Server, RDS/MySQL) and money...In general, there are the following type of companies in the MySQL commercial ecosystem, in order of total annual revenue and addressable market size:

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