What is difference between Cassandra and MongoDB?
In sum, Cassandra is the modern version of the relational database, albeit where data is grouped by column instead of row, for fast retrieval. MongoDB stores records as documents in JSON format. It has a JavaScript shell and a rich set of functions which makes it easy to work with.

To start with, both database solutions are distributed by design. With Cassandra, your data is stored in non-relational partitions just as you insert them—much like any other NoSQL platform would. MongoDB takes the NoSQL concept a step further by being document-based.
When should you not use Cassandra?
