MySQL Query Tuning Trilogy: Working with optimizer and SQL tuning (3rd and final part)

Posted in:

Join us on Tuesday, October 25th, for the third and final part of our webinar trilogy on MySQL Query Tuning, in which we look at the query tuning process and tools to help with that. So far in this trilogy we’ve covered topics such as SQL tuning, indexing, the optimizer and how to leverage EXPLAIN to gain insight into execution plans.

For Part 3, Krzysztof Książek, Senior Support Engineer at Severalnines, will now take a look at working with the optimizer as well as SQL tuning. This will include a discussion on how execution plans are calculated and a closer look at InnoDB statistics, how to hint optimizer and finally, how to optimize SQL.
