Optimizer Trace walkthrough
This video was presented at the MariaDB Server Fest, held online from 14-20 September 2020.
Optimizer Trace was introduced in MariaDB 10.4, the previous release. During the past year, it has received numerous updates and improvements.
The talk is a walkthrough of all kinds of information that one can find in the Optimizer Trace, and shows how to use it to diagnose common and not so common optimizer issues.
I will also compare MariaDB’s Optimizer Trace with MySQL’s optimizer trace, and discuss further development directions for it.
