So in playing with things a little bit, I don't think that this list of
bucket-key pairs is going to work for me.
I'm using riak counters to keep tabs of various customers ID's as they
travel through our system. So when Bob first shows up, he's seen by one
set of servers. Adding 1 to the counter for Bob within some bucket. When
he interacts with us, we'll see Bob again in another service. And thus
add 1 to another counter for Bob within another bucket.
so:
buckets/initial/counters/Bob => 1
and:
buckets/interact/counters/Bob => 1
Currently I'm using 2 MR queries to get the list of counts for all
customers from both buckets and combine these data sets within the
client. I'm trying to see if its possible to do this within 1 query.
Maybe return something like:
{"Bob": [1,1]}
in json.
I know that riak_kv_counter:value() requires a RiakObject to get the
data. I the case of a MR I know the key and that its in another bucket.
Is it possible to get the RiakObject based on those two items?

The allowable inputs to an MR map phase include a list of bucket key

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
