Understanding replication
To start with, you need to know the basic components of sharding in MongoDB. One of the
major features required for clustering in MongoDB is
replication
. Replication is a proced-
ure to synchronize data through various servers. Actually, by using replication, you can
save or copy the same data between different servers, so this redundancy can protect the
database from the data loss of a single server.
Furthermore, replication allows you to use other servers as a backup or reporting server. In
some clients, you can send read operations to another server, which results in an increase in
read capacity and performance.
