Subject distributed map-reduce queries
Date Mon, 20 Sep 2010 03:31:12 GMT
Hi Couchers,

I'm investigating using CouchDB for a data mining application and
could use some advice.

What I have in mind is sharding a collection of documents between
several instances of CouchDB each running on their own nodes. Then, I
want to run distributed map-reduce queries over the whole collection
of documents. Do I understand correctly that Lounge is currently the
way to do this?

How would doing something like this with CouchDB and Lounge compare
with using Hadoop and HBase?

Thanks for any insight!
