Sort of. One of the requirements was replication. The databases had to replicate every document so that it was stored on two different nodes. This ensures availability. The only way to do that with MongoDB is to run secondary nodes too. Now

At least you get SQL and JOINs with Couchbase.

There are a handful of databases that implement map-reduce one way or another - CouchDB, Couchbase, and MongoDB off the top of my head. Views might be a CouchDB/Couchbase concept, but not incremental map-reduce. In what way is JSON ine

Let's see if I can help here. A lot people like async map-reduce. If you need to perform aggregation on a lot of data, its constantly growing, and you need the results to be current, async map-reduce is great. In the best case scenario

TLDR - MongoDB is faster than any other NoSQL database in a benchmark published without any configuration. The results can't be reproduced let alone validated. However, in a benchmark published with all of the configuration and all of

TLDR: MongoDB benchmarked Couchbase Server by having it perform CAS operations (read + update) while MongoDB performed basic operations (update), they used an outdated client library that is two years old, and they performed it with single

It compares 9 nodes of Couchbase Server to 9 nodes of MongoDB. Couchbase Server reads and writes to every node, but MongoDB only reads and writes to primary nodes. That's the problem with active/passive topologies. MongoDB can rea

That may be true, but they both have document models and Couchbase Server will have a complete query language based on SQL, secondary indexes, and support for joins. http://docs.couchbase.com/developer/n1ql-dp4/n1q

I think it's safe to say both mobile and IoT network access is anything but reliable. Not sure if is another solution besides an embedded database with automatic sync.

Network roundtrip included. Regarding MongoDB, they are. They say MongoDB 2.8 will have document level locking. No durable configs in this benchmark though. All databases fsync'd after writes. The servers had SSDs.
