MySQL Community Advent Calendar 2022 - How to generate a slow query log using MySQL Shell on Oracle Cloud Infrastructure (OCI) MySQL HeatWave. The slow query log is a valuable tool for identifying and troubleshooting performance issues with MySQL database queries.

In my previous post about InnoDB Stalls on Empty Free List, I used a test environment that might look a little artificial : a table larger than the InnoDB Buffer Pool but fitting in the Linux Page Cache.  This configuration allows serving very quickly what MySQL thinks are IOs because these are hit in the filesystem cache.  In this post, I explain why this environment is not

Not all shapes are compatible with Read Replicas, the …
