In the previous chapter, we learned about MySQL Group Replication. We discussed Group Replication internals and also looked at its step-by-step configuration. We went through all of the important MySQL variables that can be used to fine-tune the performance of Group Replication. In this chapter, we shall focus on MySQL InnoDB, concentrating on the following topics:
- What InnoDB cluster is
- InnoDB cluster requirements
- Creating a MySQL InnoDB cluster
- Routers in InnoDB cluster
- Managing InnoDB cluster
- InnoDB cluster limitations
- Storage engines
We highly recommend that you refer to Chapter 7, Group Replication in MySQL 8.0, before proceeding with this chapter, to have a thorough understanding of Group Replication.
