      Sharding Strategy

      • Ranged-based sharding is supported.
      • The shardkey is indexed compound fields.
      • Sharding is required for all data sets in a shard instance. It is recommended to store non-sharded data in a separate replica set instance.

      Authentication Mechanism

      MongoDB is fully compatible with SCRAM-SHA-1 and MONGODB-CR.
