MySQL InnoDB Cluster and Group Replication in a Nutshell: Hands-On Tutorial

Monday 1:30PM-4:30PM

@ Swift Suite

MySQL / MariaDB

3 hours tutorial



During this tutorial, attendees will get their hands on virtual machines and migrate standard Master - Slave architecture to the new MySQL InnoDB Cluster (native Group Replication) with minimal down time. After explaining what group replication is and how it works (the magic behind it), we will experiment with multiple use cases to understand MySQL Group Replication. We will also get the attendees more comfortable with this new technology.

During our experiments, we will try to:
- Cleanly stop a node
- Kill a node
- Re-join a node
- Produce conflicts and see how the cluster behaves
- Create data inconsistency
- Recover from full cluster outage

And finally, we will check how we can integrate MySQL InnoDB Cluster with external routing solutions like ProxySQL. We will also see how to use what the cluster exposes to performance_schema and sys schema to make the right choice.
