Not Mongodb but Redis . I added Redis to my stack and I am absolutely loving it for what it does. I have SQL server for stuff that belongs in a RDBMS e.g. purchase data, accounts etc. . But the operations and analytics related stuff for my application goes into Redis. And Redis outperforms the SQL server for those purposes. If you can represent your data in terms of data structures as opposed to Table/records, you may want to take a look at Redis.
