[Proxy] When using a client such as Navicat to connect to Sharding Sphere‐ Proxy, if Sharding Sphere‐Proxy does not create a Schema or does not add a Re‐ layer interacting with the database, we call this Database Mesh. Database Mesh emphasizes how to connect distributed data‐access applications with the databases. Focusing on interaction, it effectively ${port} ${proxy_conf_directory} 2.2.4 4.

From the aspect of operation costs, when the data in a database instance has reached above the thresh‐ old, DBA’s operation pressure will also increase. The time cost of
