CouchDB is Really Quite Amazing
I've used mongoDB for a while, and it's a decent document database, but I've now been using CouchDB for a day or so, and I have to say that CouchDB beats mongoDB hands down! There just isn't any comparison - even though there may be slightly different targets, I'm not convinced that you can't do everything in CouchDB that is a "strength" of mongoDB.
The one thing that mongoDB has, that I wish CouchDB had was a nice CLI. It would be really nice to be able to do ad-hoc queries against CouchDB on the command line, but as a point of fact, you can do all that with a Temporary View… and get what you need. It's a close point, and certainly a mater of taste.
But for everything else, CouchDB is a far better implementation of a document database. The views are a fantastic feature. Their speed and power is really very impressive. I can't imagine that this is all running on my laptop. It's really pretty neat.
I think I've found my new document database - CouchDB. Fantastic!
