Are there any plans for Couch-style incrementally-computed aggregates/views in RethinkDB?

Considering RethinkDB's secondary indexes can be defined around pretty complex ReQL expressions [1] you could already get some of it already.

Yeah, I thought about that, but it seems like you can only use them to get the "map" part of map/reduce... no aggregation. Unless I'm missing something.

I think that's correct.

Yes. RethinkDB is really well set up to do this due to the underlying parallelized map/reduce infrastructure. This feature is a matter of scheduling priorities. I don't have an ETA yet, but it will almost certainly get done in the medium-term.

Awesome. If there's a Github issue about it I'd be interested to follow it.
