Part 2: MySQL InnoDB Cluster in a Nutshell: The Saga Continues with 8.0, the full guide

During this tutorial, attendees will get their hands on virtual machines and migrate standard Master-Slave architectures to the new MySQL InnoDB Cluster (native Group Replication) with minimal downtime. 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 and explain all the benefits of the new features we have introduced since 8.0.14 like the different data consistency models supported. 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 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. We will highlight the new improvements made in MySQL 8.0 regarding Group Replication and InnoDB Cluster.
