Locking down database access is probably the single most important thing for a system administrator or software developer to prevent their application from leaking its data. As MariaDB 11.8 is the first long-term supported version with a few new key security features, let’s recap what the most important things are every DBA should know about MariaDB in 2025.
The MariaDB server has over 2 million lines of code. Downloading, compiling (and re-compiling) and running the test suite can potentially consume a lot of time away from actually making the code changes and being productive. Knowing a few simple shortcuts can help avoid wasting time.
The main test system in the MariaDB open source database project is the mariadb-test-run script (inherited from mysql-test-run). It is easy to run to and does not require you to compile any source code.
Of all CI systems I’ve used during my software development career, both as developer and manager, GitLab CI has proven itself to be the overall best system out there.
