Community contributions to MariaDB

One of the goals of the MariaDB Foundation is to help new contributors understand the source code and to lower the barrier for new participants. One way to measure this is to look at the number of pull requests received and accepted, as these mostly reflect community contributions. The figures below are for the main server only, not any of the connectors or tools hosted on the Foundation’s GitHub account, and for the period 1 January to 1 July 2017.

Number of GitHub pull requests received: 126 (+113% Year-on-Year)
Number of pull requests reviewed: 102 (+76% YoY)
Number of contributors: 28 (+22% YoY)
Number of reviewers: 13 (+44% YoY)

By comparison, here are the equivalent figures for MySQL:
Number of GitHub pull requests received: 35 (-10% Year-on-Year)
Number of contributors: 19 (+27% YoY)

Although the MariaDB codebase is large and complex, we’re happy to see that there have been some interesting and important contributions from the community. …

2016 MariaDB Developers Meetup Presentations

I’ve collected slides and videos from several of the presentations given at the MariaDB Developers Meetup in Amsterdam, 6-8 October 2016. This meetup was kindly hosted by Booking.com. The presentations are listed here in roughly the order they were given. If I have both the slides and video for a given talk I link to both, otherwise I just link to what I have. The video is of poor quality as it was livestreamed to Periscope from a handheld mobile phone. Network issues also mean the streams sometimes dropped and had to be restarted. I will update this post as a receive slide decks from other speakers. …

Thoughts on MariaDB Server 10.3 from MariaDB Developers Meeting in Amsterdam, part 1

I had the honor of leading a session on Saturday, during the MariaDB Developers Meeting in Amsterdam, brainstorming around MariaDB Server 10.3. It’s definitely time to do that since MariaDB Server 10.2 has entered beta stage. In case you have missed that, I’ve wrapped up what’s included in 10.2 so far in a blog post on my employer’s site. In addition to the features mentioned in that blog post there are a couple of features still coming in 10.2 of which the most notable is that the MyRocks engine will be included. More about this later in another article. …

MariaDB Server is a true open source project

The mission of the MariaDB Foundation is to ensure continuity and open collaboration in the MariaDB ecosystem. We facilitate the development of the MariaDB Server and the related connectors as listed on our GitHub account. Core to us is to enable and foster collaboration so that contributing is meaningful and produces results for everybody.

Here are some of the things we do to ensure true open source:

MariaDB at DebConf16

At MariaDB we often get to deal with tables, but this time we took on one of a different type, and climbed to the top. We’re in Cape Town for Debconf16, and managed to take some time to climb to the top of Table Mountain.

It’s been a productive visit. Otto, who handles MariaDB packaging for Debian and Ubuntu, and is also CEO of the Foundation, hosted a BoF session on MariaDB and MySQL packaging. It’s an interesting time on the Debian packaging side, with some changes imminent, and it’s been great to see the interest and support. …
