Advanced MySQL Query Tuning (Aug. 6) and MySQL 5.6 Performance Schema (Aug. 13) webinars

I will be presenting two webinars in August:

This Wednesday’s webinar on advanced MySQL query tuning will be focused on tuning the “usual suspects”: queries with “Group By”, “Order By” and subqueries; those query types are usually perform bad in MySQL and add an additional load as MySQL may need to create a temporary table(s) or perform a filesort. New this year: I will talk more about new MySQL 5.6 features that can increase MySQL query performance for subqueries and “order by” queries.Percona MySQL webinars

Next week’s performance schema webinar will be focused on practical use of Performance Schema in MySQL 5.6. I will show real-world examples of MySQL monitoring and troubleshooting using MySQL 5.6 Performance Schema. Performance Schema can give you a lots of valuable information about MySQL internal operations. For example, if using a multi-tenant shared MySQL installation, Performance Schema can give you a lots of extensive information about your MySQL load: breakdown by user, queries, tables and schema (see more examples in my previous blog post: Using MySQL 5.6 Performance Schema in multi-tenant environments).
