Hi Mridul,
You can use filterNotFound from mapred_builtins.js...
usage format in reduce phase:
return Riak.filterNotFound(your_object_passed _from_map_phase);
Thanks,
Venkatesh

Call Riak.filterNotFound in your reduce phase.

Hi all experts,
I want to use Riak for caching and have few questions:
1) How faster is using memory back-end over bitcask back-end (on SSD)?
2) If throughput satisfying, is there any reason to use more than two nodes?
3) When my memory reaches preset limit (lets say 4Gb) what is going to
happen
Any volunteer to test EMDB as a new Riak backend:

BETS May be a good template for MDB NIFs since the MDB API looks like bdb. It
doesn't implement the Riak backend API but an ets subset.

Many thanks for all the helpful posts. BETS looks like a good starting point
for a generic MD
Hi,
I'm a beginner with Riak and map-reduce in general.
I was trying a function in map reduce which sorts the data and returns it. It
works well when all the bucket key pairs in input query exist in the riak
cluster. When a bucket/key pair does not exist, it gives an output like below.
