The latest from the MySQL community

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 …

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 […]

The final slides from René Cannaò and Alkin Tezuysal's session on ProxySQL.Cloud, BYOC architecture, configuration, and day-to-day operations.

René Cannaò and Alkin Tezuysal presented managed ProxySQL in your own AWS account at MySQL BR Conf 2026 in São Paulo.

Percona Toolkit’s pt-online-schema-change (pt-osc) has long been the preferred solution for performing online schema changes with minimal downtime. Its chunk-based copy algorithm is designed to adapt dynamically to the workload, making it suitable for very large tables in production environments.

However, under specific conditions, one of its optimization mechanisms can become counterproductive.

During a customer engagement involving Percona XtraDB Cluster (PXC), we investigated a case where running pt-online-schema-change with a selective –where clause caused severe Galera Flow Control and general overhead, effectively stalling the cluster for an extended period. The issue was not caused by the schema change itself, but by the interaction between:

• adaptive chunk auto-resizing
• highly selective copying of the newest rows
• clustered replication in Galera
• InnoDB …

MySQL 26.7 Innovation Support Lands

September 22, 2026 · ⁠GitHub Release

MySQL just changed the rules.

With MySQL 26.7, Oracle has moved to a new calendar-based versioning model for Innovation releases. For MyVector, that means one thing:

We need to keep up.

MyVector v1.26.9 adds MySQL 26.7 Innovation support, but the more interesting story is what happened beneath the surface.

This release puts the Component architecture introduced in v1.26.5 through a much more serious test.

From architecture to reliability

When we introduced the MySQL Component architecture in v1.26.5, the goal was straightforward: build MyVector in the direction MySQL itself is taking.

Now we are testing what happens when things don’t go perfectly.
