Alibaba has made lots of improvements for MySQL 8.0 in the Cloud, and will open source these patches soon.
These patches include: Performance Insight & Diagnose, New Feature and Stability Improvement. For example, we added more Object Statistics for DBAs, like CPU, LOCK and IO internal information. And we added more features for the users, like: Sequence Engine which is similar to Oracle Sequence; the Global Read-View for InnoDB, which can guarantee cross-session consistency; Async Purge File for dropping big tables; Implicit Primary Key for speeding up non-primary-key tables replication.
