couchdb

The article mentions CouchDB and other schematic-less, document DBS, which should be equally good for prototyping but suck less.

They also have a great team but appear to be much more focused on delivering the best hosted CouchDB service.

I actually started learning NoSQL on MongoDB but later switched over to CouchDB and never looked back since.

I tend to just remember the basics required to write CouchDB view functions and simple web related tasks.

Not sure about MongoDB but CouchDB has master-less peer to peer replication built in.

We plan to offer CouchDB hosting and other services under the couch.io name.

We use it in production, and we're slowly migrating some data out of SQL into CouchDB.

Cloudant is awesome for CouchDB, but if you want mongo or redis, we didn't have a lot to offer before today.

Emberjs with pouchdb and couchdb give me similar functionality (I think) with more proven technologies.

Except for not really being able to do ad-hoc queries (you write map/reduce view functions which create indices) I like CouchDB.

Maybe CouchDB or Mnesia if you know for sure that you need their replication features and are aware of the tradeoffs of using a non-relational database.

Cassandra, HBase, CouchDB etc even MongoDB have built in scalability as a first order priority from day one and have been largely successful at it e.g.

They also acquired Cloudant, a CouchDB based "Cloud Database." Side-thought: Did Compose refer to itself as a Cloud Database before IBM acquired it?
