Document database

MongoDB is a Document database

that provides high performance, high availability, and automatic scaling.

A record in MongoDB is a document

which is a data structure composed of field and value pairs. (similar to JSON objects)

high availability AND automatic scaling

Replica set (a group of MongoDB servers that maintain the same data set), provides:

  • automatic failover
  • data redundancy

Sharding distributes data across a cluster of machines.

Storage Engine

  • WiredTiger Storage Engine (including support for Encryption at Rest)
