You can easily compare the Mongo documents to the JSON documents since the former is mirroring the latter. A worth-mentioning feature of this database is the easy structure change of the record which facilitates the hierarchical relationships, delicate data structures, and store arrays. You can easily store documents of any type, size, content, and field in one single collection of the database via a schema-less database with great flexibility. MongoDB makes data retrieval from the pool quite easy because it incorporates indexed documents using primary and secondary indices. It aids in accessing data even if it is corrupted or a server fails to retrieve it, by replicating and spreading data over numerous servers. This data sharing over many servers is done by sharding which allows horizontal scalability. MongoDB has spread its wings to the major titans of the industry like Google, Facebook, eBay, and Adobe, and is providing storage services to them.

You can save time by only learning about the basics of Redis in minutes and can start storing data in it. Another major benefit is that you will be able to set expiry times to strings which is an important component for caching. These features make it a perfect solution for data distribution and caching. you will require other databases along with Redis to fully support the complex applications because it alone can not handle the complexity of a few applications.
