Feed: Planet MySQL; Author: Øystein Grøvlen; This blog post is inspired by Jesper's recent blog post on how the automatic update of InnoDB persistent statistics may never trigger if servers are restarted frequently.

The discussion is about why some of that data makes the news every day, while some other critical parts of that same public data set ... Read More
