Automatic Upgrade and New Error Logging in MySQL 8.0

We will cover upgrade from MySQL 5.7 to MySQL 8.0 (8.0.15), going from legacy metadata storage to transactional data dictionary. We will cover the new possibilities for automation of upgrade, and the major advances in upgrade speed and reliability, as well as new consistency checks in the MySQL upgrade checker. MySQL 8.0 has a pluggable error log. We will talk about the traditional error logger and the JSON error logger, which empowers users with advanced filtering.
