FOSDEM 2021 CfP now open

Earlier this week we were happy to announce that MariaDB will have its own devroom at FOSDEM21, taking place on 6 February 2021, and now the CfP is open.

FOSDEM is free to attend, and no registration is necessary. It’s aimed at free and open-source developers, so engineering and DBA-related topics such as:

  • best practices
  • migrating to MariaDB
  • MariaDB features
  • optimising on particular hardware

are all welcome. Submissions that miss the mark, such as marketing talks, are not welcome.

We are expecting far more submissions than we can accommodate, so we are looking for 20 minute talks (with an extra 5m for questions) to accommodate as many high-quality speakers as possible.

MariaDB DevRoom at FOSDEM

Great news! MariaDB got its own DevRoom at FOSDEM 6-7 Feb 2021. Usually FOSDEM happens in Brussels, but nobody is surprised that it is virtual this year.

What FOSDEM is

FOSDEM is the biggest Free and Open Source Developers Meeting worldwide. I am sure it remains so in these pandemic times. While I will miss all the many social f2f encounters at FOSDEM, I am looking forward to meeting people virtually.

Separating MariaDB from MySQL

For MariaDB Foundation, this is no small challenge. We will have to establish a Program Committee of our own, when we have so far cohabitated with MySQL.

MariaDB Server MiniFest Wed 9 Dec 2020

New MariaDB releases come with regular intervals. Releasing a new version is a balance between new functionality and bugfixes on one side, and stability on the other. How do we get optimum quality for the releases? And what exactly is quality, from the point of view of DBAs and developers that use MariaDB Server?

That’s the setting of our MariaDB Server MiniFest in two weeks.

New MariaDB Releases: The DBA & Developer Experience 

This MiniFest is called “mini” for three key reasons:

  1. It has just one topic
  2. It is much shorter, less than half a day
  3. It happens just in one time zone

But it still builds on the pillars of success from our MariaDB Server Fest in Sep 2020:

  1. It features expert speakers on MariaDB Server
  2. It has pre-recording, subtitles, and follow-up discussions
  3. It is interactive, with the speakers “cloned” on Zulip chat

The special sauce

The special sauce for this MiniFest is

  1. Internal presenters explain the logic of release policies
  2. External presenters give the candid user perspective
  3. The desired outcome: improved processes and quality

The conference format

The internal (provider) presentations have a 10+10 minute format.

Making MariaDB understand MySQL JSON

Good news for MySQL users wishing to upgrade to MariaDB: MariaDB 10.5.7 onwards understands formerly-incompatible MySQL JSON fields! This blog entry explains how to install and use them.

Introducing MYSQL_JSON plugin

Starting from MariaDB 10.5.7 (commit f6549e), it is possible to upgrade from MySQL 5.7 tables containing JSON by loading the MYSQL_JSON data type plugin.

MariaDB and MySQL JSON formats are not the same. In MySQL, the JSON type is a native type, while in MariaDB JSON is just an alias for LONGTEXT. What this means in practice is that data in JSON format are not compatible with each other.

Emergency Release of MariaDB 10.5.8, 10.4.17, 10.3.27, and 10.2.36 is now available

The MariaDB Foundation is pleased to announce the availability of MariaDB 10.5.8, MariaDB 10.4.17, MariaDB 10.3.27, and MariaDB 10.2.36, the latest stable releases in their respective series.

Why do we release MariaDB again only a week after the 10.5.7, 10.4.16, etc? What’s the emergency?

The previous, scheduled, set of releases (10.2 and up) included a security related change — MariaDB server became more strict about accepting network packets from the client. It never was particularly trusting, but still there was a loophole in the handling of prepared statements where the server just assumed that the client sends the correct data. …

MariaDB & Ecosystem Fragmentation

We hear you, Kristian Köhntopp! Thank you  for taking the time to articulate what many others are probably thinking.

For those of you to whom this sounds cryptic, let me share how I interpreted Kristian Köhntopp’s blog MySQL: Ecosystem fragmentation (
), published last week:

Kristian noted that the question “Which version of MySQL do you run on?” for a long time hasn’t been merely answered by a simple version number, since there are reasons to perceive MariaDB and Aurora to be “variations to the same theme”. 

MariaDB 10.5.7, 10.4.16, 10.3.26, 10.2.35 and 10.1.48 now available

The MariaDB Foundation is pleased to announce the availability of MariaDB 10.5.7, MariaDB 10.4.16, MariaDB 10.3.26, MariaDB 10.2.35 and MariaDB 10.1.48, the latest stable releases in their respective series.
