preFOSDEM MySQL Belgian Days 2026 Recap: Real-World Ops, New Features, and RockStar Moments
Right before FOSDEM kicked off, the preFOSDEM MySQL Belgian Days returned to the usual place in Brussels for two packed days (Jan 29-30, 2026). The format stayed true to what makes this event special: a friendly, hallway-track-heavy gathering with serious technical content — this year running two parallel tracks and the grand final: the RockStars […]
Introducing MySQL Backup Export in MySQL HeatWave
We are pleased to introduce the ability to export MySQL HeatWave backup data directly to an OCI Object Storage bucket in your tenancy, enabling a one-step process to create an exported backup via the Console or API. This process creates a logical dump from the backup without utilizing DB system resources, thereby minimizing the impact on the […]

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:
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.
No More Hidden Changes: How MySQL 9.6 Transforms Foreign Key Management
MySQL is taking a significant step forward by rethinking how foreign key constraints and cascades are managed. Starting with MySQL 9.6, foreign key checks and cascade operations will be handled directly by the SQL engine rather than the InnoDB storage engine. This improvement addresses long-standing challenges with change tracking, binary log replication, and data consistency, making […]

I have a curse. My curse is curiosity.
Here in Percona I found one person that is very “dangerous” for me, and he and I also share the same first name, well almost, Marcos Albe.
Marcos is a smart guy with a lot of ideas, and he is not shy to share them. One day we were talking about sysbench, and he mentioned to me: you know it would be nice to have a test for joins in sysbench. I wonder why we don’t have it; it will be so useful to identify regressions in that area.
You see where this is going right? He put…
