MySQL InnoDB Cluster
MySQL is a relational database management system that stores structured data in tables and serves it over SQL; InnoDB Cluster is its native high-availability feature, combining Group Replication, the MySQL Shell AdminAPI, and MySQL Router to keep a set of instances synchronized with automatic failover.
Baseline topologies
