  • Just in case someone is still confused when to use column based DBs here's a little explaination: Consider a database which has a large volume of data with 100 columns. And your application most of the time just queries only a few columns (let’s say 4-5 columns). Then in case of document DBs or row based DBs (relational Dbs) all data will be loaded row by row in main memory for processing , parsing and other operations. It will be a waste of a lot of effort in loading and processing of unnecessary columns. Column based DBs are used to tackle this problem where a large amount of data is stored in column based fashion so that the application can query only a few columns of large volume of data. - reference: Designing Data-Intensive Applications. by Martin Kleppmann.
