Hello,
I have a question regarding the use of 2i. I've read some of the benefits (like
less writes when inserting data) of using 2i instead of links when modeling
data and it seems this is the preferred option nowadays when using Ripple
(Ruby).
I now have some data that keeps links (and links back) in a hierarchical tree
like (or parent-child like) structure storing sensor data. It allows us to
drill down (and up) from
country<->state<->city<->street<->device<->monthly_collection<->daily_collection<->records
and we can use MapReduce jobs like this (Ruby code):
devices = Riak::MapReduce.new(Ripple::client).add("countries", 'USA').
link(:bucket=>"state").link(:bucket=>"city").
link(:bucket=>"street").link(:bucket=>"device").
map("function(v){ return [v.key]; }", :keep => true).run
Is there a way that 2i could be used instead of links and what would the
MapReduce query look like?
Thanks,
Timo
