Summary

The text discusses how to profile the memory usage of a MySQL connection using built-in mechanisms in MySQL. It covers memory statistics, finding usage for a connection, collecting usage over time, and plotting memory usage with visualizations. The author provides Python scripts that can be used to monitor memory usage during query execution and generate live stack plots showing the top memory usage categories. This detailed profiling of memory usage can help in identifying when and why MySQL may cause memory pressure on the system or if a memory upgrade for the database server is needed.
