Hi,
so if I understand that right (and the erlang api seems a little
easier to understand in that regard):
If I want multiple map phases, the "previous" map phase basically just
acts as a filter/expansion for the input data. If I emit a {Bucket,
Key} term Riak will then load this document and pass it into the next
phase. So if I have a Document with multiple references to others I
may expand the input data running a map phase which basically just
emits those links as {Buckey, Key} terms. Basically a (huge)
optimization over doing something similar on the client side.
Dont have a great example right now, but I get the idea (I think).
Thanks,
/thomas
