What is secondary or slave in mongodb?

Question Posted / priya nigam


What is secondary or slave in mongodb?..

Answer / Ishwar Chand

In MongoDB, a secondary (or slave) is a replica set member that maintains a copy of the primary's data. The role of secondaries is to provide redundancy and high availability by taking over the read operations when the primary goes down. You can configure multiple secondaries in a replica set to achieve higher fault tolerance.
