Naturally there are two reasons for why you need to access MongoDB from R:
- MongoDB is already used for whatever reason and you want to analyze the data stored therein
- You decide you want store your data in MongoDB instead of using native R technology like data.table or data.frame
In-memory data storage like data.table is very fast especially for numerical data, provided the data actually fits into your RAM – but even then MongoDB comes along with a bag of goodies making it a tempting choice for a number of use cases:
- Flexible schema-less data structures
- spatial and textual indexing
- spatial queries
- persistence of data
- easily accessible from other languages and systems
In case you would like to learn more about MongoDB then I have good news for you – MongoDB Inc. provides a number of very well made online courses catering to various languages. An overview you may find here.
