The recently released MariaDB 10.5 GA includes many new, useful features, but I’d like to concentrate on those helping DBAs and support engineers to find out what’s going on when a problem occurs.

Specifically I’d like to present and discuss the Performance Schema updates to match MySQL 5.7 instrumentation, new tables in the INFORMATION_SCHEMA to monitor the internals of a generic thread pool and improvements of ANALYZE for statements.
