MySQL 8 Features for Developers covers the big changes in the popular database.  The big change is a true transactional data dictionary, which means your database is not tied to the file system; the good news is that you can now can have millions of tables in a database schema, and the bad news if that you now can have millions of tables in a database schema.  We've improved the JSON data type support and added a NoSQL JSON document store (no more embedding ugly strings of Structured Query Language in your code). Plus there are resource groups, CTEs, windowing functions for analytics, roles, histograms, and more.  If you want to get the most out of your MySQL database, come to this session.
