As we set out to help the MySQL ecosystem assert greater independence from Oracle by establishing a vendor-neutral industry association, we had to confront a deceptively simple question: What exactly is the MySQL ecosystem? There are many views on this question. Some argue it should revolve strictly around the MySQL brand—meaning MariaDB would be excluded. […]

What Happened at the Summits We just wrapped up two MySQL Community Summits – one in San Francisco in January, and one in Brussels right before FOSDEM. The energy in the rooms: a lot of people who care deeply about MySQL got together, exchanged ideas, and left with a clear sense that we need to […]

When a replica fails due to corruption or drift, the standard solution is to rebuild it from a fresh copy of the master when pt-table-sync is not an option. Traditionally, when we need to build a new replica, we use a physical backup for speed, but there are some cases where you still need logical […]

This article is focused on describing the latest performance benchmarking executed on the latest releases of Community MySQL, Percona Server for MySQL and MariaDB.  In this set of tests I have used the machine described here.  Assumptions There are many ways to run tests, and we know that results may vary depending on how you […]

Over the past weeks, we have seen renewed discussion/concern in the MySQL community around claims that “Oracle has stopped developing MySQL” or that “MySQL is being abandoned.” These concerns were amplified by graphs showing an apparent halt in GitHub commits after October 2025, as well as by blog posts and forum discussions that interpreted these […]

A unique constraint specifies, one or more columns as unique it identifies. It is satisfied only when no two rows store the same non-null values at its core. A primary key constraint is a unique one that will say PRIMARY KEY in its defined way. It is satisfied only when rows unfold, and none may […]

When we run databases in Kubernetes, we quickly learn one important truth: things will fail, and we need to be prepared for this. Pods are ephemeral; nodes can come and go, storage is abstracted behind PersistentVolumes and can be either local to a node or backed by network storage, and Kubernetes moves workloads as needed […]

Where We Are We can all agree that the MySQL ecosystem isn’t in great shape right now. Take a look at Julia’s blog post [Analyzing the Heartbeat of the MySQL Server: A Look at Repository Statistics], which confirms what many of us have felt: Oracle isn’t as committed to MySQL and its ecosystem as it […]

The MySQL database server is a foundational component of the open-source world. While its impact is undeniable, looking at the raw statistics of its core source code repository reveals a dynamic and sometimes surprising development history. By analyzing the total lines of code inserted, the number of commits over the years, and unique contributors, we […]

In a recent post, The Quirks of Index Maintenance in Open Source Databases, I compared the IO load generated by open source databases while inserting rows in a table with many secondary indexes. Because of its change buffer, InnoDB was the most efficient solution. However, that’s not the end of the story. Evolution of the […]
