Upgrading to MySQL 8 0 Michael Coburn at Percona
Upgrading to MySQL 8.0 is on everyone's roadmap for 2023 - This talk teaches how we do it at Percona!
Processes we'll cover:
How to fail over with zero downtime
How to deploy & tune a replication hierarchy, and methods to ensure that the data is consistent
How to identify queries which perform more slowly, or generate different results in MySQL 8
How to monitor your environment during the upgrade preparation & failover windows, which graphs to keep top of mind, and how to fall in love with the watch command
Don't forget that MySQL 5.7 goes End of Life October, 2023 - that's only 5 months away!
