MariaDB 10.10 preview releases now available

We are pleased to announce the fourth MariaDB series release under the new release model, MariaDB 10.10.0.

Maturing MariaDB more quickly

One of the purposes of the new model is to get features into the hands of users more quickly, in a form which supports stability by allowing the new feature to be more easily tested, separate from other new features being developed at the same time.

Candidate features for MariaDB 10.10

There are four separate preview releases, containing the following features under consideration for release in 10.10.1:


  1. Change defaults for CHANGE MASTER TO so that GTID-based replication is used by default if master supports it (MDEV-19801)

We’re hiring: Senior MariaDB Developer / Code Reviewers

Yes, we are hiring! 

And we are hiring for quite an interesting position: As a senior developer of MariaDB Server, with merging community code contributions as a main task.

A demanding job

This is a very demanding job. The MariaDB Server code base is large and complex, and being a good C / C++ developer is only the starting point for being able to contribute to it. You also need to understand databases, and the existing codebase architecture.

A demanding code base

The existing codebase is demanding. Depending on how you look at it, it’s either very efficient (if you know it well), or it has many dependencies (if you don’t).

MariaDB replication using containers

In this blog we are going to demonstrate how to replicate a MariaDB database that runs in a Docker container (let’s call it primary) to one or more MariaDB servers that run in a Docker container (let’s call them replicas) using binary logging, a method that creates binary log files and an index that contains the record of all changes to the database (both data and structure). You can find an overview of how replication works here and you can find how to setup replication here. An example can be found in this GitHub script.

Contributions, our lifeblood

The lifeblood of MariaDB Foundation is contributions. Our trinity consists of the fundamental values of Adoption (of MariaDB Server), Openness (of the MariaDB Server codebase), and Continuity (of our operations and activities), all of which are centered around MariaDB Server. We rely on our financial sponsors to finance our activities, but the financial value of the code contributions we receive outshines the total sponsorship payments. That has been the case every year since MariaDB Server was launched.

Giving recognition to code contributions

The MariaDB Foundation has not given proper recognition to this fact, of the value of our contributions.

China Has Great Potential for MariaDB Server

Our Board Meeting in April 2022 elected two seasoned new voting board members. One of them is Xiang Peng (Sean), Director, RDS Open Source Databases at Alibaba Cloud. I had the pleasure of having a Fireside Chat with him, which we recorded and put up on YouTube. Read on for his recommendations for MariaDB Foundation in China.

A Man With the Right CV for MariaDB Foundation

Sean, as he calls himself for those of us who have problems remembering, reading or writing his real name 彭祥, is a great resource for MariaDB Foundation.

Cyber Protection – best practices for backing up data

A few weeks ago we hosted a webinar together with Acronis and CPanel on security and backup best practices as both provide software in this space. Acronis develops Cyber Security cloud based software particularly specializing in backup and disaster recovery for other service providers. CPanel in turn helps those service providers to enable their customers to administer their systems via a fully fledged dashboard. The webinar was a follow-up on another join presentation at CloudFest. The webinar presented quite a number of good ideas and I highly recommend you watch it.

Celebrating Olivier Bertrand of the CONNECT Engine

Please join MariaDB Foundation in giving a bit of financial recognition to Olivier Bertrand, the developer behind the CONNECT Storage Engine! We will match your contribution up to a total of 5.000 €, on top of the 5.000 € that we have already allocated 5000 € for Olivier Bertrand’s Lifetime MariaDB Contribution Award.

What is CONNECT?

Olivier Bertrand is an unsung hero. He is the original contributor and still the main developer behind the CONNECT Storage Engine, which – much as its descriptive name indicates – enables MariaDB Server users to connect to a variety of databases other than MariaDB Server itself.
