Introducing ‘MySQL 101,’ a 2-day intensive educational track at Percona Live this April 15-16

Talking with Percona Live attendees last year I heard a couple of common themes. First, people told me that there is a lot of great advanced content at Percona Live but there is not much for people just starting to learn the ropes with MySQL. Second, they would like us to find a way to make such basic content less expensive.

I’m pleased to say we’re able to accommodate both of these wishes this year at Percona Live! We have created a two-day intensive track called “MySQL 101” that runs April 15-16.

And of course it’s ideal for anyone else who would like to expand their professional experience to include MySQL. The sessions are designed to lay a solid foundation on many aspects of MySQL development, design and …

And if this is a database issue, then it must involve IO problems because the reason for a slow database is always a slow IO…”  Following this logic might actually give a result, but achieving a fully successful resolution would require magic.

At Percona we use a different approach. Performance optimization should not be based on guesses, but exact measurements. In application to databases, I described previously, we use queries as units of work. And a proper measurement of these units is the first important task in …
