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.

Performing schema changes often requires extended downtime for applications. This is due to MySQL needing to rebuild tables for common schema change operations. Tools like pt-online-schema-change have been written to try to overcome the downtime associated with schema changes, however they are complex and put a high load on the database.

Continuent has traditionally had a relaxed policy about Linux platform support for customers using our products.

While it is possible to install and run Continuent Tungsten products (i.e. Cluster/Replicator/etc.) inside Docker containers, there are many reasons why this is not a good idea.

Today we’re happy to announce that we’ll be partnering with Datavail to provide solutions for continuous & highly available MySQL, Percona Server & MariaDB database operations based on Tungsten Clustering & Datavail Database Services.

This blog explains why the Tungsten rollback error exists and why it's important.

In this blog post we will discuss how the managed cross-site replication streams work in a Composite Multi-Master Tungsten Cluster for MySQL, MariaDB and Percona Server.

We’re one of the two Diamond Sponsors at this year’s Percona Live Conference in Austin and this blog provides an overview of our participation, including the talks we’ll be giving, such as on moving MySQL data in real-time into Amazon Redshift and on the colour of open source money.

From time to time we are asked how to check whether or not there are data discrepancies between Master/Slave nodes within a MySQL (or MariaDB) cluster that's managed with Tungsten Clustering.

This blog covers INI vs Staging configurations for Secure Shell.

In this blog post we will discuss how to best integrate various Continuent-bundled cluster monitoring solutions with PagerDuty (pagerduty.com), a popular alerting service.

Our colleague Matt Lang walks you through a comparison of building a global, multi-region MySQL / MariaDB / Percona cloud back-end using AWS Aurora versus Continuent Tungsten.
