I am not sure if you got the April’s 1st CouchDB announcement:
So, after a lot of heated discussion internally, I’m somewhat sad to say that Erlang will not be used in future releases of CouchDB. We are switching the whole codebase to (…drumroll..) Java.
I don’t know how many have fallen for it (must confess that even if I am an easy target this one didn’t work for me), but reading something like this on April 1st is not always trustworthy.
However, a couple of days later a part of the announcement is becoming reality: FeatherDB – Java JSON Document database
According to the post:
FeatherDB was my attempt at a Java clone of CouchDB.
There were a few things about the way CouchDB handles documents that I didn’t like, so FeatherDB does things a little bit differently.
You should check the original post as it contains a lot of more details about what and how FeatherDB does and how it is comparing with CouchDB
