Hi,
I'm still new to the underpinnings of working with MapReduce in Riak.
That being said I think what you're looking for is possible, though I'm
sure someone else might be able to share a better way with you.
Using some custom code(
http://docs.basho.com/riak/latest/ops/advanced/install-custom-code/) you
could write what you're looking for.
_NOTE_, this is untested... you've been warned!
getMetaData(RiakObject, _KeyData, _Arg) ->
Key = riak_object:key(RiakObject),
Data = riak_object:get_metadata(RiakObject),
[ {Key, Data} ].

Hello:
I'm trying to understand how to do a map/reduce referring to meta-data.
Example (I'm using JavaScript).
I have a meta-data field called X-Riak-Meta-start-time; the contents of which
are a Unix timestamp.
I'd like to find all keys with a timestamp older than now() - 30 days ago.
Reading through the documentation this seems to be straight forward if I was
looking at the actual data being stored, however, I'm simply unclear as to how
to do while looking at a MetaData field.
Appreciate any help you can provide.
