We’ve made significant progress on MariaDB Catalogs, and while there’s still work to be done, we’re excited to offer the community an easy way to try out our preview release. You no longer need to compile the source code yourself—just use our prebuilt containers, now available on our official quay.io development registry.
The code is available publicly on Github, in a separate repo compared to the official MariaDB Server (until the feature gets published as part of an official MariaDB Server release)
Documentation is available on the Knowledge Base.

MariaDB uses Clang’s memory, address, and undefined behavior sanitizers are used for identify coding flaws during the continuous development and testing process. MariaDB would like to share via an online event on how easy perform the same sanitizer checking.
The MemorySanitizer environment is particularly onerous to create. Because MariaDB use container based build and testing, we have an environment that can be re-used by anyone.
Our “Deep Dives” were once an internal skills transfer mechanism, however for the first time we’re making it available for anyone to join.
This particular deep dive will cover:
- Basics of MemorySanitizer, Address Santizer and Undefined Behavour Sanitizer;

Shortly, we will start coding a task, for which we would appreciate your input: How would you like to DROP USER?
Why do we ask?
DROP user (originating in MySQL in 2004) always used to just drop the account from the privilege tables, but left all existing connections active. You can argue that this was questionable in 2004, but it’s really unexpected and confusing in 2025, with MariaDB being ubiquitous as it is.
So now we’re considering changing it.
But changing a 20-year-old behavior cannot be done lightly. We want to ask
you, our users, what would you prefer DROP USER to do.

This past Friday was reserved for our very own cozy event in Bucharest, planned by the romanian squad of the MariaDB Foundation. With an audience ranging from students just starting out on their journey up to seniors with experience in multiple database servers and AI, lots of interesting talks took place. We were glad to meet the Head of Domains and IT Technology of our gold sponsor, IONOS.
Although not his first visit in Romania, Monty’s attendance was a welcome sight, even bringing in people from the Czech Republic and the United Kingdom.

We had the pleasure on Friday to take individual calls with everybody who submitted to the ideation phase of the MariaDB AI RAG hackathon.
The ideation phase deadline passed last week, and we are happy to share that we received several promising submissions for both the innovation track and the integration track. Innovation involves applications using MariaDB Vector, like RAG, and integration being enabling MariaDB Vector in an existing framework.
Participants range from individual contributors to even a corporate team. Some already have some experience with AI, and some are newcomers to RAG.

The ideation phase of the MariaDB AI RAG Hackathon is nearing its deadline on Monday (by end of March).
We have several cool submissions so far. One is about combining the Knowledge Graph and LLMs, using MariaDB Vector Nearest Neighbour Search. Another one is about an “advanced context diff”, identifying the differences between two text corpuses based not on their literal wording, but on their content.
All of the current submissions are in the Innovation track. We would particularly like submissions in the Integration track – to add MariaDB to frameworks such as these, or other apps.

One week left to join the AI RAG Hackathon with MariaDB Vector and Python!
Winners get to demo at the Helsinki Python meetup in May, receive merit and publicity from MariaDB Foundation and Open Ocean Capital, and prizes from Finnish verkkokauppa.com.
To participate, gather a team (1-5 people) and submit an idea by the end of March for one of the two tracks. You then have until May 5th to develop the idea before the meetup 27th May.
- Integration track: Enable MariaDB Vector in an existing open source project or AI-framework.

We are excited to announce a hackathon with MariaDB Vector and Python. Since we are reaching outside our bubble, let’s start from the beginning:
MariaDB, the open-source database powers the world’s most demanding applications, from Wikipedia to global financial institutions. Now MariaDB Vector is bringing AI-ready vector search natively into the open-source database world. MySQL users ahoy:
Our hackathon is your chance to explore AI possibilities with MariaDB Vector and Python. Whether you’re a developer, data scientist, or AI enthusiast, MariaDB Foundation invites you to build innovative AI applications, compete for prizes, and showcase your work.
