Slides from Percona Live talks: optimizer tutorial and Cassandra Storage Engine

I’ve put online the slides for the two talks that I сo-presented at the Percona Live conference:

The tutorial tries to cover most areas of the optimizer, with focus being on optimization of complex parts of SQL like joins. It also shows how recent additions in MySQL and MariaDB (PERFORMANCE_SCHEMA, SHOW EXPLAIN, EXPLAIN FORMAT=JSON, optimizer_trace) can be useful when diagnosing optimizer problems.

The Cassandra talk starts with an introduction into Cassandra and Cassandra Storage Engine, and then proceeds to discuss the intended use cases for Cassandra Storage Engine. This is an important discussion, because there is a variety of reasons one might want to access Cassandra’s data from SQL, and Cassandra Storage Engine addresses only certain kinds of needs.
