Single-host cluster deployment that simulates sharding as a replica set

Overview

You can use a single data server as a shard or a replica set as a shard.

The replica set is a master-slave cluster with the automatic fault recovery function, and its master-slave role can be changed automatically.

Each replica set includes three roles: master server, slave server, and arbitration server.
