We are pleased to welcome Sylvain Arbaudie as a sponsor of the MariaDB Foundation.
Sylvain Arbaudie is an independent consultant with extensive experience helping organisations design reliable, scalable data infrastructures. Having worked primarily with commercial systems early in his career, Sylvain has witnessed how open source has matured into a powerful foundation for innovation, technological sovereignty, and long-term freedom—often surpassing proprietary alternatives in robustness and adaptability.
Among relational databases he has followed—MySQL, PostgreSQL, and MariaDB—Sylvain sees MariaDB as standing apart through its clarity of design, integrated ecosystem, and enterprise-grade reliability. These qualities make it a strong choice for organisations of all sizes, from individual founders to global enterprises.

The MariaDB Foundation is pleased to welcome HammerDB as a Silver Sponsor.
HammerDB is the industry-standard open-source database benchmark, widely used across the database, cloud, and hardware ecosystem to evaluate mission-critical performance, scalability, and real-world workload behaviour. Its transparent and reproducible workloads are trusted by practitioners and vendors alike when validating performance claims, comparing configurations, and understanding database behaviour under load.
HammerDB is developed independently and hosted by the TPC Council as part of the TPC-OSS program, providing a neutral and credible reference point for performance evaluation.
HammerDB has long supported MariaDB and is frequently used by the community to test new releases, investigate performance regressions, and build confidence in production deployments.

At the MariaDB Foundation, clarity of purpose matters. In an ecosystem as foundational as open-source databases, confidence is built not through slogans, but through predictability, restraint, and long-term commitment.
As I reflect upon what we learned in 2025 and how we can serve the database community in 2026, one thought stands out: MariaDB is the natural successor to MySQL, as Oracle loses its interest in the development of what has been the default Open Source Relational DBMS.
The MariaDB Foundation recognises its responsibility. As uncertainty around MySQL’s long-term direction continues to grow, the global community of users, operators, and vendors quite reasonably seeks continuity.

It’s the time of the year to look back and reflect. In line with the holiday spirit, we’d like to highlight some of the MariaDB Server contributions from 2025 that the team found particularly inspiring and interesting, and to say thank you to everyone who submitted them.
At the end of the post, we invite the community to help us recognise the most impactful external contributions of the year.
- MDEV-36737 Research and Estimation for Adapting VIDEX to MariaDB: thank you, Haibo Yang (YoungHypo) and Rong Kang (kr11) from ByteDance for this very interesting contribution.

The Queen’s Seven Predictions for 2026
When Queen Isabella I of Castile agreed to fund Columbus, it was not because the idea felt daring or exciting. It was because the old routes were failing. Europe’s trade system had become expensive, fragile, and constrained, and maintaining it unchanged was no longer a neutral decision. Supporting the voyage was not an act of romance, but of governance: an acceptance that continuing as before carried greater risk than change.
Crucially, nothing collapsed overnight. Trade still flowed. Goods still arrived. But every journey became longer, costlier, and more politically exposed.

In October 2025, we launched the first State of MariaDB Survey to learn how the community really uses MariaDB. Today, we’re excited to share the results.
Why we did this
We wanted to move beyond assumptions and get real data from the people who work with MariaDB every day—developers, DBAs, architects, consultants, and everyone in between. The goal was simple: understand how MariaDB is actually being used so we can make it better.
What we learned
The survey covered seven areas: background and experience, organizational use, use cases, tech stacks, deployment practices, challenges, and community engagement.

We recently announced the winners of the MariaDB Python Hackathon. We sat down with the Innovation track second place winners to learn more about the team and their submission.
Sunny Kumar, Abhijeet Dhanotiya, Anuj Gupta, Tushan Kumar Sinha, and Anand Vyas developed Metadata-Hub, a multimodal semantic search application using MariaDB Vector and OpenAI’s CLIP model. 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 interview below.
