What we’ve developed in 2024

As Chief Development Officer of the MariaDB Foundation, I’ve worked to ensure that our development efforts focus where they matter most. On this final day of 2024, I want to reflect on the significant technical achievements we’ve accomplished and the collaborative processes that made them possible.

Our work this year has been driven by the goal of building a stronger, more engaged MariaDB community. By sharing our progress and learnings, I hope to provide insights that may inspire and support other open-source projects.

Finally, I’ll outline the Foundation’s vision for 2025 and how we plan to bring it to life.

Talk: The implementation of MariaDB parallel replication

On November 6 2024 I presented a talk with the title: “The implementation of MariaDB parallel replication” at a local TeqHub meetup in Copenhagen.

In the talk I first presented how MariaDB replication works overall. I then described the central idea of optimistic parallel replication. Finally I described three details of the implementation: transaction scheduling; conflict detection; and efficient commit ordering. Here are the slides for the presentation.

I was very impressed by the level of the engagement of the audience. There were many questions that showed not only a deep interest in the subject, but also a deep understanding of the material I presented.

Announcing the first MariaDB Hackathon – in India!

Update 2024-10-15: The event has been cancelled in favour of something better. Please see the end of this post.

On the 24th – 25th October 2024 we will be hosting our first-ever Hackathon as part of our larger MariaDB Foundation presence around Open Source India.

What is a Hackathon?

If you have never done one before, it is basically a fun and challenging technology event where the goal is to create new things. Attendees are split into small teams of 5-10 people. An open source project is chosen to create and/or improve upon, and you have a day to work on it (and night as well if you really want to).

Finally here: MariaDB Vector Preview!

We’re here, we’re open source, and we have RDBMS based Vector Search for you! With the release of MariaDB 11.6 Vector Preview, the MariaDB Server ecosystem can finally check out how the long-awaited Vector Search functionality of MariaDB Server works. The effort is a result of collaborative work by employees of MariaDB plc, MariaDB Foundation and contributors, particularly from Amazon AWS. 

Previously on “MariaDB Vector”

If you’re new to Vector, this is what’s happened so far:

The main point: MariaDB Vector is ready for experimentation 

MariaDB Server GitHub branches: Moving to “main”

On the 3rd of July, two weeks ago, I created a poll to ask about the future of feature development branches in MariaDB Server. Specifically, whether we should switch to a rolling model which is more familiar to users of services such as GitHub.

The votes we received gave a very clear result. Today I will share the conclusions we drew, as well as setting expectations for what will happen next.

Recap: what is this “main” branch all about?

In a rolling model, there is one main branch of the tree that all the feature commits go into (typically called “main”), and this is then forked when it is time to prepare a major release.

Improving MariaDB support in open source projects

As part of MariaDB’s efforts in Adoption, we have been working on support of MariaDB in open source projects. 

The open source projects we have been looking at range from well known, ready to use projects like WordPress or MediaWiki (that Wikipedia runs on), to under-the-hood solutions like ORMs that connect software with databases for countless other open source and private projects.

MariaDB is the de facto standard that many projects and users are running. As MariaDB diverges, matures and develops on its own path from MySQL, especially in later versions, it’s not enough to shrug off compatibility questions with “MariaDB is a drop-in MySQL replacement – everybody knows that”.

Start of Life for MariaDB 11.6

We normally announce releases and the end of life of releases, but today we are going to try something a little different, an announcement of “start of life”.

What does this mean?

The way we use GitHub is a little different to most projects. Instead of having a mainline and branching versions from that, MariaDB Server creates a new branch from the previous version. This is intended to happen shortly after the preview release of the previous version, but for various reasons it can come a little later. So by default, after the hypothetical version 11.7.0 is released, we will create the 11.8 branch in GitHub soon after.

How Intel helps MariaDB become even faster

There are many forums in the past couple of years where I have talked about how non-code contributions are just as important to MariaDB Server and us at the MariaDB Foundation as the code contributions I typically help with. I’ve also highlighted in the past how Intel have provided some fantastic non-code contributions. They assist us by detecting performance issues on their new and future platforms, as well guidance in finding the root cause of these issues.

The outcome: Over a million NOPM in HammerDB

Today I want to discuss some of the performance improvements that Intel has helped with, which have led to MariaDB Server achieving 1 million NOPM (new orders per minute) in the HammerDB TPROC-C test.
