  • Sharding is used to create a cluster of MongoDB instances consisting of at least three servers.
  • There are three types of elements in Sharded Cluster.
      1. Shards
      2. Query Router
      3. Config server

    Elements of sharded cluster

    Shards :

    • It is a single MongoDB instance that holds a subset of the sharded data.
    • It can be deployed as replica sets to provide redundancy and increase availability.
    • The combination of multiple shards creates a complete data set.

    Query router :

    • Query router acts as a Mongos providing a stable interface between the application and the sharded cluster.
    • In this MongoDB instance is responsible for routing the client requests to the correct shard.

    Config Server :

    • Config Server becomes to store the metadata (Data about the data) and the configuration settings for the whole cluster.
