Performing MySQL schema changes often requires downtime for applications. In this blog, we cover two ways we can perform MySQL schema changes without risking downtime or other MySQL data problems. In this real-life customer example, we perform a schema change to modify the column data type from varchar(20) to varchar(50) on approx. 35 tables from 3GB to 10GB in size. Two of the tables are partitioned, and one of them is about 100GB combining all partitions for that table.

This blog provides basic information about business-critical application to database connections; my team focuses on MySQL, MariaDB, and Percona Server for MySQL on Linux/Unix that’s infrastructure-agnostic (on-prem, VM, hybrid-cloud, cloud, multi-cloud, etc.).

This blog discusses some best practices for using multiple filesystems on MySQL database servers and how to achieve the best performance with them, while avoiding some of the possible pitfalls.

An overview of a Tungsten topology that doesn’t get much attention: the Cluster-Slave, which is an easy way to get data resiliency and integration, with features that make it ideal for big data analytics, reporting, and backups.

Version 6+ of Tungsten Clustering comes with a host of improvements for your Multi-Site Multi-Master topology (MSMM); this is partly why it has a new name: Composite Master-Master (CMM). Probably the most notable improvement is that the Managers are more aware. What does that mean?

The Tungsten Connector is an intelligent MySQL proxy that provides key high-availability and read-scaling features. This includes the ability to route MySQL queries by inspecting them in-flight.
