We recently announced the winners of the MariaDB Hackathon at the BangPypers meetup in Bengaluru. We are now interviewing the winner submissions, continuing with the Integration track second place winner.
We sat down with Ria Kulkarni and Revanth Sreeram Ambati who developed a Dagster integration for MariaDB, bringing modern data orchestration capabilities to the MariaDB ecosystem. They were interviewed by Robert Silén, Community Advocate and Kaj Arnö, Executive Chairman of MariaDB Foundation.
For the recorded interview, watch it on Youtube, or read the summary below.
First, let us repeat a short introduction on the topic of data orchestration that we also shared in the interview with the Airflow Integration track winner.

We recently announced the winners of the MariaDB Hackathon at the BangPypers meetup in Bengaluru. We sat down with the Integration track first place winner to learn more about the team and their submission.
Pratush Maheshwari and Jyothi Muthuraj developed an Apache Airflow integration for MariaDB, addressing a significant gap in the data engineering ecosystem. They were interviewed by Robert Silén, Community Advocate and Kaj Arnö, Executive Chairman of MariaDB Foundation. For the recorded interview, watch it on Youtube, or read the summary below.
But first, a short introduction to the topic of data orchestration.

Last Saturday marked an exciting milestone: the announcement of the winners in our first large-scale MariaDB Python Hackathon, organised in collaboration with BangPypers, HackerEarth, and MariaDB plc. Over the past months, developers from across India have explored new ways to make MariaDB easier to use, more connected, and better integrated into today’s most important open-source ecosystems.
This post celebrates the outstanding contributions in both the Integration Track — projects that help MariaDB work seamlessly with other tools and frameworks – and the Innovation Track – projects that showcase existing MariaDB features and make it easy to learn, copy, and adapt.

The final days are here for the Foundation’s first large-scale hackathon, the MariaDB Python Hackathon we’re organising in partnership with BangPypers (the Bangalore Python Meetup, a group with about 14,000 members) and HackerEarth (a Hackathon organiser). Do come with your final submissions of ideas at mariadb-python.hackerearth.com within the next two days – in October, it’s development time!
The magnitude is new for MariaDB Foundation
Already, we’re quite proud of the results. Last Wednesday, I reported to the MariaDB Foundation Board meeting that we have over 3,000 registered individuals and 250 team idea submissions.

A framework that doesn’t make you cry.
Stay tuned to learn how you can get involved and contribute to the project!
If you don’t known what Buildbot is and what benefits it brings to MariaDB please check out this this quick introduction.
🤔 Just, why?
Over the years, the Buildbot project within MariaDB has undergone numerous transformations, constantly shaped by the requirements it needed to meet.
When I joined MariaDB in 2024, I was initially a bit overwhelmed by the complexity of the codebase, a complexity that later turned out to stem mainly from the intertwining of implementation details with the simple core principles of BuildBot, such as builders, factories, builds, and workers.

One of the standout features of Oracle PL/SQL is the associative array — a versatile and efficient in-memory data structure that developers rely on for fast temporary lookups, streamlined batch processing, and dynamic report generation.
With the MariaDB 12.1 preview release, we’re excited to announce that associative arrays have landed in MariaDB as part of our growing set of Oracle compatibility features. This milestone, tracked under MDEV-34319, brings Oracle-style associative arrays into the MariaDB procedural language — complete with native type declarations, variable construction, and method support.
Let’s explore what’s included, what’s different, and how this feature was implemented from the ground up.

We recently announced the winners of the MariaDB AI RAG hackathon that we organized together with the Helsinki Python meetup group. Let’s deep dive into the integration track winner. David Ramos chose to contribute a MariaDB integration for MCP Server. MariaDB plc was impressed by the results and has picked it up for further development with more features.
David, tell us about yourself and why you decided to join the Hackathon?
I am an aspiring Data Scientist from Colombia. I studied Physics in college, but by the time I graduated, I realized what I enjoyed the most was working with data and programming, so I decided to make the shift to Data Science.

We at MariaDB Foundation are thrilled to see Amazon at the forefront of applying artificial intelligence to open source contributions — with MariaDB as their pilot.
At the May 6th MariaDB meetup in Bremen, Bardia Hassanzadeh, PhD, presented the Upstream Pilot tool: an AI-based assistant designed to help developers identify, analyze, and resolve open issues in MariaDB more effectively.
This initiative is the most promising we’ve seen for improving the open source contribution process. Bardia and Hugo Wen of Amazon gave us a preview last week and we were already very impressed.
