Missed our recent Deep Dive on New-Style Query Optimizer Hints? The full recording is now available on YouTube: https://lnkd.in/dvkGS3Hy In this session, Sergei Petrunia (MariaDB plc) walks through the new optimizer hint syntax in MariaDB. He begins by discussing the origins of this hint syntax in Oracle and MySQL. Then, he explores how MariaDB’s hints are compatible with MySQL, and what additional hints MariaDB offers. The talk dives deep into the technical details—examining what hints really mean for the query optimizer and highlighting issues with MySQL’s hint implementation. Sergei also shows how one of these problems was solved by TiDB and discusses whether that approach could work in MariaDB. Watch this talk if you want to truly understand why and how query optimizer hints work—and become a real hint wizard. #MariaDB #MariaDBCommunity #MariaDBFoundation #OpenSource #Database #SQL #DatabasePerformance #QueryOptimization #DBA #BackendDevelopment

Doctrine's DBAL made a release 4.3.1 https://lnkd.in/g6cUe4Qg that included a MariaDB fix. This is significant because a nightly test against MariaDB's latest container image discovered that a miscellaneous improvement in the 12.1 preview - https://lnkd.in/gJQHhvDT , Per-table unique FOREIGN KEY constraint names (MDEV-28933), introduced a small compatibility issue. DBAL wasn't quoting foreign key names in the particular 4.3 release series and via a test case of DBAL, discovered this incompatibility. These nightly test cases were created a year ago from information in https://lnkd.in/gDNg7hQ6, where the test failure messaged to our Zulip instance. When messaged I promptly took action to understand what changed. So within a week, there's a fixed version of DBAL for a MariaDB that isn't even released. If the problem happened to be on MariaDB's end we had a chance to fix this before a GA version without any compatibility issues arising. DBAL is just one of many projects using MariaDB's development versions to ensure that our common users are getting the best MariaDB experience with their project. Is the compatibility of your project/infrastructure with MariaDB important enough for you/your users? If so you can message me to see how we can best integrate the CI, potentially even triggered by new versions in our CI. This is made possible with MariaDB Foundation and our sponsors (please make that you!) that keep this and many other community efforts going, so as a user, the experience is bliss.

🎉 Happy AI Appreciation Day, everyone! It’s amazing to see how far we’ve come—from rule-based systems to living, learning models that power real-time insights. Huge props to the AI community for pushing boundaries every single day. At the MariaDB Foundation and MariaDB, we’re riding that wave with our MariaDB #Vector integration, which has supercharged our vector search capabilities and unlocked some seriously cool use cases. Here’s to the researchers, engineers, and dreamers making AI smarter, fairer, and more useful than ever! 🚀🤖
