Feed: Planet MySQL; Author: Andrew Grimo; MySQL introduced the MySQL “Upgrade Checker” initially to support upgrades from MySQL 5.7 to 8.0 series. However, the continuous development initiative in the MySQL 8.0 release series has continued this tools usefulness as it can also report on continuous delivered features throughout the MySQL 8.0 release life. Additionally, “Yes”, bug fixes are always part of that development release cycle too. As a heads up, here is the documentation. I also show samples of the tools capabilities at the end of the post.

Feed: Planet MySQL; Author: Kristian Köhntopp; My task is to collect performance data about a single query, using PERFORMANCE_SCHEMA (P_S for short) in MySQL, to ship it elsewhere for integration with other data. In a grander scheme of things, I will need to define what performance data from a query I am actually interested in. I will also need to find a way to attribute the query (as seen on the server) to a point in the codebase of the client, which is not always easy when an ORM or other SQL generator is being used. And finally I will ... Read More
