Jeremy Lewi commented on CRUNCH-306:
------------------------------------
For my particular use case (Contrail) a PGroupedTable which writes each key to a different
instance of the target is sufficient.
My PGrouped table will be a mapping: String key->Array(Avro Records). I want the records
associated with each key to be written to file named something like "key.avro". A nice feature
would be able to supply a function which computes the output file as a function of the key.

> A commonly desired feature for Crunch is the ability to write an output file for each
key in a PTable/PGroupedTable containing the values associated with that key. We should find
a way to support that one-output-per-key model.
