Speaking at Percona Live New York

As the top MySQL expert in New York it is great to join the team at Percona for the upcoming Percona Live in New York City on May 26th. As an invited speaker I am joining a select list of expert speakers including Harrison Fisk from Facebook, Kurt von Finck from Monty Program and Monty Taylor from the core Drizzle team.

My presentation will be on Improving Performance with Better Indexes where I will not only show how to apply indexes to improve query performance, but how to apply better indexes and provide even greater performance gains via a great technique known as a covering index.
