It does not seem to support streams, does it ? It's a module which enables use of mongodb semantics without using mongodb itself, which is a good idea on itself ! Though, what I wanted to know is whether or not there exists a stream manipulation API. Maybe something like spouts and bolts from twitter storm project : - https://github.com/nathanmarz/storm - http://www.slideshare.net/nathanmarz/storm-distributed-and-faulttolerant-realtime-computation
I think that node.js streams are a powerful interface, usually under used by module writters. There ought to be some stream manipulation (grouping, sorting, joining) outhere which would open the way for amazing use cases like twitter's storm. Anyone with same vision ?
