Mining the MySQL Performance Schema

— "The MySQL Performance Schema is a gold mine of valuable data. Among the many nuggets you can extract from it is an historical report of transactions: how long a transaction took to execute, what queries were executed in it (with query metrics), and idle time between queries. Mining this information is not trivial, but it’s fun and this blog post shows how to start.

— "To my knowledge, there are currently no open-source tools that mine the Performance Schema and process the raw data into something easy and useful for human consumption. The MySQL sys Schema has many views that use raw Performance Schema data, but that’s still pretty raw and incapable of expressing a full transaction as shown here. Plus, the Performance Schema has a lot more data than I showed here, so the industry really needs a sophisticated tool that can extract and refine the vast wealth of data in the Performance Schema into gold: deep and practically completely insight into MySQL performance.
