Virtualisation has been a very popular technique for both development and production systems for many years. It allows multiple software environments to run on the same physical machine.
Containerisation takes this idea even further. It allows you to segment your software environment down to the level of individual software packages. This means you can install multiple copies of MariaDB on one system, and run them in parallel while keeping them isolated from each other.
This is a very powerful technique when doing development because you can quickly test different versions of the software. It also allows you to experiment with clusters: you can create a complete Galera database cluster on a single computer! …
The MariaDB Foundation has had 2 projects accepted for Google Summer of Code 2018, of which one we deemed successful. Teodor Niculescu (teodorvicentiuniculescu@gmail.com)’s work was part of an effort to improve MariaDB’s query optimiser by providing faster histogram collection using equal-width histograms. His project is not yet in a release worthy state, yet we are working alongside him to get it feature complete (hopefully for our 10.4 version). We are glad that Teodor has chosen to present his work at the MariaDB Developer Unconference in Tampere and also remain within the community, although currently busy with his studies as is expected. …

Here is a quick tip for any developer who might want to test if the latest development version of MariaDB installs/upgrades. Traditionally, developers seem to have a bunch of virtual machines lying around which they use to test MariaDB installation and upgrade related things. Snapshotting virtual images, keeping them up-to-date, starting, stopping etc. takes a lot of time and does not feel very convenient.
A much faster option would be to use pristine Docker images for every test. Docker images however normally only run one process and thus do not simulate a complete operating system and lack vital things like systemd interactions. …

In order to ensure that new (or changed) code does not break anything, there is an extensive test suite that is run to catch regressions during MariaDB Server development. Developers are expected to run the test suite locally and, after pushing the code to the remote repository, also check that the more extensive tests run on Travis CI and in particular Buildbot do not find any regressions either. However, sometimes developers are sloppy, make mistakes, don’t check the test results and in a hurry to just push their code change on the main branches, and then the test suite gives errors for everybody else from that point on. …
