MySQL Enterprise Backup and MySQL Enterprise Audit are exclusive to the Enterprise Edition. These features provide advanced backup and security auditing capabilities essential for enterprise environments.

The binary log records all changes made to the database (such as updates, inserts, and deletes). These logs are used to replicate these changes to the replica servers.

server_id uniquely identifies each server in a replication setup, and log_bin enables binary logging, which is crucial for replication as it logs all changes made to the database.

Synchronous replication in MySQL InnoDB Cluster ensures that all nodes have applied the changes before a transaction is considered committed. This guarantees data consistency across the entire cluster.

The HeatWave Cluster accelerates query performance by using parallel processing of analytical queries across distributed nodes, and it allows for real-time analytics by executing queries in-memory.
