New optimizer features in MariaDB releases before 10.12


This talk will cover new MariaDB query optimizer features other than the Cost Model Rewrite in MariaDB 10.12.

We’ll describe the new features in MariaDB 10.8-10.11 that were added since the 2021 MariaDB Server Fest. They are smaller features but they’re already in the stable releases so you can already benefit from them.
