As previously noted, title is misleading. Also, pick a better document store (though you should note that rethink only guarantees operations on single documents as atomic): http://rethinkdb.com/ http://rethinkdb.com/ Yes, "better" is subjective, but rethink has a good page detailing the differences (between rethink and mongo): http://www.rethinkdb.com/docs/rethinkdb-vs-mongodb/ http://www.rethinkdb.com/docs/rethinkdb-vs-mongodb/ Feature-list type breakdown: http://www.rethinkdb.com/docs/comparison-tables/ http://www.rethinkdb.com/docs/comparison-tables/ And pay attention to the guarantees that it provides/doesn't provide when you pick. I think this is a big part of what separates novice developers form middle-tier developers. There are always tons of choices, for just about everything in software these days, and your job is to figure out how best to solve which problem you're facing, in a way that future generations won't hate you for.
