Important news: MariaDB 10.11, which just was declared RC, is a long-term maintenance version. The industry standard term to refer to that concept is LTS (as in long-term support), and we too use this term for the releases that get a significantly longer lifetime of bug fixes.
We are announcing MariaDB 10.11 as LTS for a number of reasons:
Firstly, the purpose of an LTS is to reassure users – and, in particular, Linux distros – that a certain version will receive regular updates long-term, for the lifetime of their product.
…
The MariaDB Foundation is pleased to announce the availability of MariaDB 10.11.1, the first release candidate in the MariaDB 10.11 series, and MariaDB 10.10.2 the first generally available release in the short-term MariaDB 10.10 series.
See the release notes and changelogs for details.

MariaDB 10.11.0, our latest preview release, features quite a number of improvements. The one we’ll talk about here is replicate-rewrite-db. This option has become a system variable from 10.11.0 based on MDEV-15530. Before this version it was just an option used by the mariadbd and mariadb-binlog binaries. There have been no behaviour changes with the option; it has simply become a dynamic variable.
How to try out this feature
The fastest way is to take MariaDB 10.11 for a spin in docker / podman (consult the blog mariadb-replication-using-containers) with the following commands:
To start a primary 10.11.0 MariaDB container, clone the directory, navigate to the cloned directory and run the following command:
docker run -d –rm –name mariadb-primary \
-v $PWD/config-files/primarycnf:/etc/mysql/conf.d:z \
-v $PWD/primaryinit:/docker-entrypoint-initdb.d:z \
-v $PWD/log-files-primary:/var/lib/mysql \
-e MARIADB_ALLOW_EMPTY_ROOT_PASSWORD=True \
quay.io/mariadb-foundation/mariadb-devel:10.11
To start the replica/secondary run the command to start the mariadbd process as well as specify the replicate-rewrite-db option on the command line:
docker run -d –rm –name mariadb-secondary-1 \
-v $PWD/config-files/secondary-1:/etc/mysql/conf.d:z \
-v $PWD/secondaryinit:/docker-entrypoint-initdb.d:z \
-v $PWD/log-files-secondary-1:/var/lib/mysql \
-e MARIADB_ALLOW_EMPTY_ROOT_PASSWORD=True \
quay.io/mariadb-foundation/mariadb-devel:10.11 –replicate-rewrite-db=’db1->db2′
Besides specifying the option as a command line argument, you can use a configuration file.

FOSDEM 2023 is happily once again going to be an in-person event, and MariaDB will be participating as part of the MariaDB, MySQL and Friends devroom. The Call for Papers is now open.
FOSDEM 2023 will take place on Sat 4 to Sun 5 February 2023 at the ULB Solbosch Campus, Brussels, Belgium.
There are some changes in the organization to previous years. MySQL and MariaDB will each be responsible for its own track, so we will divide the devroom in two sub-tracks.
For the convenience of the speakers and participants, we will not mix the two sub-tracks, and you will have the possibility to follow either track you are interested in, or of course both. …

I’m going to start this blog post by saying that I made a mistake, a mistake that means all of the metrics blog posts so far have been made with erroneous data. As part of our openness value I will give a post-mortem of the issue here.
Metrics generation
Before we look into what went wrong, I first need to give a bit of background. The commit metrics are generated using a tool called “gitdm”, this is a “Git Data Miner” that was designed to generate commit statistics for the Linux Kernel. Our fork of this is in the metrics repository which includes some customisations that fit MariaDB Server’s needs better.

Yes, it is a bit of a click-bait title, but in this case running one SQL command did improve a community user’s performance by that much. It could help you too.
The story
A community user posted in a couple of places that when migrating a large WordPress installation to MariaDB that they were seeing a certain query performing terribly. The query was taking 1.5 seconds to execute and it was clear from the explain plan that the optimizer was not making an ideal decision about the join order.
The query was generated by WordPress so it would not be easy to force an index, or rewrite the query.

MariaDB 10.11.0, our latest preview release, features quite a number of improvements. The one we’ll talk about today is GRANT … TO PUBLIC.
Background
MariaDB has quite a complex privilege system. Most of it is based on the SQL Standard spec; however we do have some specific MariaDB extensions. GRANT … TO PUBLIC (MDEV-5215) is a standard feature that is now available as a preview in MariaDB 10.11.0. It is related to ROLES and DEFAULT ROLE, but it covers a different use case.
ROLES are effectively “privilege packages” that you can enable and disable as a user.
