MyCat Bin Log vs. MySQL Bin Log: Key Differences Explained

MyCat and MySQL both utilize bin logs to record database operations, but they have distinct differences:

1. Target Scope: MyCat's bin log focuses on distributed databases, tracking changes across the cluster, while MySQL's bin log records operations within a single instance.

2. Sharded Table Support: MyCat's bin log can log operations on sharded tables, whereas MySQL's bin log doesn't handle this scenario.

3. Query Logging: MyCat's bin log captures query operations on sharded tables, while MySQL's bin log lacks this capability.

4. Log Format Flexibility: MyCat's bin log supports diverse formats like JSON and Protobuf, offering more options than MySQL's binary-only format.

5. Configurable Control: MyCat's bin log allows precise control over recorded operations through configuration, surpassing MySQL's configuration-based approach.

In essence, MyCat's bin log stands out with its flexibility, richer feature set, and tailored design for distributed database environments, providing a more comprehensive and adaptable solution compared to MySQL's native bin log.
