CouchDB project is in the process of merging BigCouch into mainline CouchDB.

https://issues.apache.org/jira/browse/COUCHDB-1843

Keep an eye on this if interested in future of clustering in CouchDB.

Nice! Is there a timeline for this that you know of..?

As far as I know folks should be able to continue to use the Cloudant project with CouchDB until it's merged. I personally haven't used it recently, but do work with CouchDB regularly.

Looking at the big picture though, the main project is committed to this direction, so it's definitely worth spending the time if interested in DynamoDB-style clustering (or clustering in general) in CouchDB.

Thanks! I'm researching the topic, I'll take a good look.

I suppose the author meant converting some JSON to a map using something like Jackson which has SON to map conversion integrated.

Also I find this only relevant for single level JSON, if you have nested objects or arrays I do not see this working.

Jackson is Java, though. If you use Cassandra's native solution you can store and query JSON objects from any client that can do CQL...

(correct me if I'm wrong)

map != json... it will work for you in non nested cases though.

Yeah, for nested objects other NoSQL databases are the answer. Still cool I think.
