Our most recent MariaDB Server release introduced some regressions starting with the 10.6 series, affecting 10.7 – 10.9 as well. This blog post is here to explain the problems in hopes that the impact is minimized. We are likely going to release a new version of MariaDB correcting these problems soon.
InnoDB Full Text Index on tables causes an assertion error (MDEV-29342)
There was a bug in the InnoDB Storage Engine where the full text index could go out of sync with the actual table data. This would happen when only one new row was inserted between the last InnoDB sync (which happens asynchronously) and a server shutdown.

I have been working for the MariaDB Foundation as the Chief Contributions Officer for a couple of weeks and it is fantastic being part of the MariaDB family again. Part of my job is to help the community massage pull requests into something that we can merge. I am, however, finding that one of the worst parts of my job is having to say “no” to contributions that clearly took a lot of time and effort on the part of the developer.
Contributions could be turned down or at least will require changes for a number of reasons.

Would you like to contribute to the MariaDB Server code base, its feature set, its quality? Here’s what you can do to help – in other words, here’s our Contribution Wish List
Scratching your own itch
The assumption around code contributions is usually that the code contributor extends the product in a direction that corresponds to the contributor’s own needs, which in turn are close to the needs of other users. “Scratching your own itch” is the phrase commonly used.
Some itches are more for the common good
That said, we have also been approached by potential providers of contributions that would take a more general approach.

In the previous blog we have seen how to create a statefulset MariaDB application. Also, we learned how replication works in MariaDB in this blog. Now, we will try to create a replicated statefulset application. As good references for creating this blog, I would like to give credit to the Kubernetes documentation as well as an example from Alibaba Cloud.
Configure replication
To replicate a MariaDB application we are going to create a statefulset that will consist of a single init container and one application container.

The MariaDB Foundation relies on public mirrors to distribute binaries and packages to the world. An overview of the full list can be seen at https://mirmon.mariadb.org. If you would like to volunteer to become a mirror, take a look at https://mariadb.com/kb/en/mirror-sites-for-mariadb/.
Our download page already automatically suggests one of those mirrors for you to download our binaries. Same goes for the repository configuration tool; see https://mariadb.org/download.
The purpose of this blog post is to present you a new system that we have been testing since December 2021 and that we believe is now ready for public adoption.

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).

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.

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.
