Three key points about MySQL InnoDB Cluster and NDB Cluster:
1. MySQL InnoDB Cluster and NDB Cluster both provide high availability solutions for MySQL applications, with InnoDB Cluster using the InnoDB storage engine and NDB Cluster using the NDB storage engine.
2. InnoDB Cluster provides a simpler configuration and administration experience compared to NDB Cluster, but NDB Cluster offers additional capabilities like automatic sharding and native NoSQL APIs.
3. Oracle's vision is for MySQL InnoDB Cluster to become the primary high availability and scaling solution for MySQL, with all components integrated into a single MySQL product for easy setup and management.
