Benchmarking MyRocks vs. InnoDB in Memory-Constrained Environments It is a well-known fact in the database world that InnoDB is incredibly fast when the entire database fits into memory. But what happens when your data grows beyond your available RAM? MyRocks, built on RocksDB, is frequently recommended as a superior choice for environments constrained by memory, […]

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. […]

Modern applications often rely on multiple services to provide fast, reliable, and scalable responses. A common and highly effective architecture involves an application, a persistent database (like MySQL), and a high-speed cache service (like Valkey). In this guide, we’ll explore how to integrate these components effectively using Python to dramatically improve your application’s performance. Understanding […]

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 […]

The replication  manager script can be particularly useful in complex PXC/Galera topologies that require Async/Multi-source replication. This will ease the auto source and replica failover to ensure all replication channels are healthy and in sync. If certain nodes shouldn’t  be part of a async/multi-source replication, we can disable the replication manager script there to tightly controlled the flow. Alternatively, node participation can be controlled by adjusting the weights in the percona.weight table, allowing replication behavior to be managed more precisely.

At Percona, open source is not just something we use. It is who we are. From our earliest days, our mission has been simple and consistent: make open source databases better for everyone. That mission guides our product decisions, our business model, and how we engage with the community. Today, I want to share an […]

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 […]
