From single MySQL instance to HA
FOSDEM 2021

During this session, I will show how we can start from a single instance to MySQL InnoDB Cluster, the automated HA solution for MySQL, passing by the following architecture:

  1. Single MySQL
  2. Source / Asynchronous Replica
  3. InnoDB ReplicaSet
  4. InnoDB Cluster

I will cover the limitations of each options and how to migrate from one to the next one with minimal downtime.
