MongoDB Replica Collection

#简述: Replica collection (Replica sets), a replication feature based on the master/slave replication mechanism, but with the addition of automatic failover and recovery features, a cluster can support up to 7 servers, and any node can be the primary node. All writes are distributed to the master node, and the read operation can be performed on any node;
