Abstract :
The replication mechanism of NoSQL database MongoDB includes Master/Slave structure and Replica Set. Write operation implement on Master, Slaves will send the synchronize data command asynchronously to Master to update its data. Read operation just implement on Master to provide the strong consistency, while read operation implement on Slave to provide the eventual consistency. Replica set is a group of servers which run Mongod and store the copy of the same data with automatic failover and automatic recovery of member nodes.
