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 some problem happens. Specifically, I'd like to present and discuss 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.
MariaDB 10.5 Enterprise may add more troubleshooting features, especially for Galera, and assuming this really happens they are also going to be presented briefly.
The goal of this session is to show new ways to understand solving performance problems now available in MariaDB 10.5.
