    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 wa…

    "Did they test against a single MongoDB server or cluster?" Couchbase: 9 nodes on 9 AWS instances (1 node per instance). MongoDB: 18 nodes on 9 AWS instances (1 primary and 1 secon…

    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.co…
