Hi! First of all, I'm new to Riak, so maybe my question doesn't make sense :)
Doing some tests with map/reduce, I experienced a huge performance difference between link walking and map/reduce: I run Riak on a single box for testing, I have 2 buckets, 'artists' have 500 objects, and albums have nearly 3000 objects. All objects are very small, a small string as data. curl http://localhost:8098/buckets/artists/keys/pink_floyd/albums,author,_ was nearly immediate, it took 0.156s while: curl -X POST -H "content-type:application/json" \ http://localhost:8098/mapred --data @- {"inputs":[["artists","pink_floyd"]],"query":[{"link":{"bucket":"albums","tag":"author"}},{"map":{"language":"javascript","source":"function(v) { return [v]; }"}}]} Took nearly 2 seconds. Is there a reason for such a speed difference? Is the map/reduce performance expected?
