MySQL InnoDB Cluster

1. High Availability: Ensures continuous database availability with automatic failover.

2. Built-in Replication: Utilizes MySQL Group Replication for real-time data replication.

3. Automatic Failover: Handles failover scenarios seamlessly to minimize downtime.

4. Integrated Management: Simplifies setup, configuration, and monitoring with MySQL Shell and Router.

5. Scalability: Easily scales database infrastructure by adding or removing nodes.

Before learning MySQL InnoDB Cluster, it's beneficial to have:

1. MySQL Database Knowledge: Understanding of MySQL database fundamentals, including SQL queries, database design, and administration.
