Mongo#
The Mongo module provides a MongoDB-based version of the DBContextStorage class.
This class is used to store and retrieve context data in a MongoDB.
It allows the DFF to easily store and retrieve context data in a format that is highly scalable
and easy to work with.
MongoDB is a widely-used, open-source NoSQL database that is known for its scalability and performance. It stores data in a format similar to JSON, making it easy to work with the data in a variety of programming languages and environments. Additionally, MongoDB is highly scalable and can handle large amounts of data and high levels of read and write traffic.
