The latest from the MySQL community

At a recent discussion with MySQL ACEs and Rockstars, we were asked a fair question: If a bug is fixed in one supported MySQL LTS series, why isn’t it always fixed in another? A quick refresher: LTS means Long-Term Support. Within an LTS series, MySQL aims to keep the feature set and data format stable […]

MySQL is very good at serving application workloads, but things get more complicated when somebody decides to run a large report on the same server.

A scan can push hot pages out of the buffer pool. A long-running read can hold back purge. A GROUP BY over millions of rows can start writing temporary tables to disk.

The traditional answer is a reporting replica. But that means running another MySQL server, and at the end of the day it is still a row-oriented database.

Another option is moving the data into an analytical database. That can work very well, but now you have a data pipeline to build, operate, monitor, and eventually debug.

We have been looking at what MySQL users can do with DuckDB, and DBTrail is an interesting approach.

DBTrail is open source under Apache 2.0. It is being built by Daniel Guzman-Burgos, who previously worked at Percona as a MySQL Technical Lead.

Type “a heist that goes wrong in a snowy town” and get back real films, with posters, in a few milliseconds. The vector search behind it runs inside MySQL, with no separate vector database.

Movie Finder is the new demo app that ships with MyVector. It searches up to 1,035,695 TMDB movies by meaning, not keywords. One docker compose up gives you the whole thing: MySQL 9.7 with the MyVector component, a loader, and a small web app.

Try it live: https://demo.myvector.online/

We built it to answer the questions people ask us most. Does vector search in MySQL hold up at a million rows? Can I mix it with ordinary WHERE filters? What happens when I insert a new row? The demo shows the answers on the page, with the SQL that ran under every result.

Thread Pool in Percona Server and MySQL (Part 1)

A new version of Community MySQL Server July release contains two versions 26.7.0 and 9.7.2. It is an important milestone because it finally brings a Thread Pooling feature to the community. The official MySQL Server Thread Pool plugin existed for a long time, but was available exclusively for MySQL Enterprise Edition.

Before MySQL 26.7.0 / 9.7.2 the most popular free thread pooling enabled alternatives were:

• Percona Server for MySQL, which shipped Thread Pool functionality as a plugin
• MariaDB with the Thread Pooling built into the server
• Third-party plugins such as xiezhenye/mysql-plugin-threadpool available on GitHub

Now we will be able to see what benefits the thread pooling mechanism brings to MySQL Server and compare it with the implementation of the thread pool in Percona Server for MySQL.

Part 1 will explain the …

Oracle patching carries operational risk. The traditional approach, manual in-place updates, leaves limited margin for error. One misstep in an Oracle software home can mean hours of unplanned downtime and a difficult root-cause conversation afterward.

In our recent Where can you find MySQL from August through October 2026?, we shared a broad view of MySQL conferences, community activities, and user group meetups. Since then, community gatherings in Denver, Taipei, and Nashville have brought MySQL users, developers, and contributors together for technical discussion and local connection. We are continuing that momentum […]

A status with angle brackets appears as text in the feed rather than turning into page markup. I appreciate that line breaks also stay visible, so a longer update reads more like what was typed. A submitted status gives you a concrete path into the feed. See how the app saves that update so the […]
