New Era of MySQL Community Engagement
Pre-FOSDEM & FOSDEM 2026, Community, Databases, and Open Source
This is a recap of Percona at preFosdem and Fosdem!
Before FOSDEM officially started, the database community gathered for MySQL Belgium Days (Pre-FOSDEM), a two-day event bringing together MySQL developers, DBAs, engineers, tool builders, and open-source enthusiasts. It was an excellent space for deep technical discussions, knowledge sharing, and reconnecting with the community, hosted by the amazing Frederic Descamps. The event featured strong participation from Percona and the wider MySQL ecosystem, with talks led by …

PGDay and FOSDEM Report from Kai
The following thoughts and comments are completely my personal opinion and do not reflect my employers thoughts or beliefs. If you don’t like anything in this post, reach out to me directly, so I can ignore it ;-).
I’m currently on the train on my way back home from FOSDEM this year and man, I’m exhausted but also happy. Why? Because the PG and FOSDEM community is just crazily awesome. While it’s always too much of everything, it’s at the same time inspiring to see so many enthusiastic IT nerds in one place, discussing and working on what they love - technology and engineering…
Hackorum - A Forum-Style View of pg-hackers
Last year at pgconf.dev, there was a discussion about improving the user interface for the PostgreSQL hackers mailing list, which is the main communication channel for PostgreSQL core development. Based on that discussion, I want to share a small project we have been working on:
Hackorum provides a read-only (for now) web view of the mailing list with a more forum-like presentation. It is a work-in-progress proof of concept, and we are primarily looking for feedback on whether this approach is useful and what we…
Tuning MySQL for Performance: The Variables That Actually Matter
There is a special kind of boredom that only database people know. The kind where you stare at a server humming along and think, surely there is something here I can tune. Good news: there is.
This post walks through the most important MySQL variables to tune for performance, why they matter, and when touching them helps versus when it quietly makes things worse. This is written with InnoDB-first workloads in mind, because let’s be honest, that’s almost everyone.

MySQL January 2026 Performance review
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.
AssumptionsThere are many ways to run tests, and we know that results may vary depending on how you play with many factors, like the environment or the MySQL server settings. However, if we compare several versions of the same product on the same platform, it is logical to assume that all the versions will have the same “chance” to…
OIDC in PostgreSQL: With Keycloak
We spent a long time, two blog posts to be specific, talking about OAuth/OIDC in theory. Now we’ll take a more practical look at the topic: how can we configure PostgreSQL with a popular open source identity provider, Keycloak, and our pg_oidc_validator plugin?
We’ll not only look at the PostgreSQL configuration part, but also discuss the environment requirements and setting up Keycloak.
Docker containersIf you are only interested in trying out a working demo installation, we have a ready-to-use Docker Compose configuration available in our…
