Why we use Replication in MongoDB and its benefits?
In MongoDB replication is one of the process to synchronize data on multiple servers. With replication data is redundant and will have multiple copies of data on different database servers. And replication will protects data from loss as this will be available on multiple server. And replication will also helps to recover data from hardware failure and service interruptions. As we have multiple server with same data we will dedicate one as disaster recovery, reporting or for backup. And below is th facts why replication is used:-
(1)Replication help to keep our data safe.
(2)Replication helps in disaster recovery.
(3)Replication helps to data availability to 24*7
(4)Here we donot need a downtime for maintenance for example backup, index rebuilds and compaction.
(5)Replication will also helps in Read scaling as we have extra copies of data
(6)Replica set is transparent to application | |
