#couchdb does not support chaining of map/reduce jobs. people in mailing lists suggest creating temporary databases that will hold the output of the map function(again a json doc) and run map jobs on it. Will work like a charm. Sounds like what we do in traditional RDBMS world. Chaining map/reduce is basic to any map/reduce based db is what i thought. Will that be added to future versions of couchdb? Any thoughts?
