Thank you for the quick response Jeremiah.
I didn't know that inputs could accept a list of buckets. I do believe
that will solve my problem.
I'm currently using MR to grab a list all keys/counters and use the
reduce phase to sort the keys by highest count. Because I'm using
counters the backend MR quires are in erlang. The query would be ad hoc,
I guess, because the client would be retrieving the data at frequent but
not known or consist times.
Thanks again for the answer!

Can you describe a bit more about how you're using MR? Is this an ad
hoc query? A predictable report? Time based?

Hi All,
I have a question concerning map-reduce. I have two buckets with
counters enabled that have similar keys to track two different
metrics. At the moment in order to combine these two datasets
together I have to make 2 different map-reduce queries and combine
the data within the client. I'm wondering if/how it might be
possible to combine both of these queries into one. I'm thinking
that Links are a possibility, but I'm not sure if it would or how
viable a solution it would be.
Any and all advice is welcomed.
Thanks in advance,
Bryce
