A bit more digging has shed some light on the issue I'm seeing. I am using a custom built protocol buffer client, and it would appear that Riak is sending back more than 1 response for the map reduce job, which seems odd to me. The first response contains - The expected content payload - Ha

Re: Speed of linkwalking

Re: Speed of linkwalking

I'm actually testing with an object that has only one link as that's my use-case. In testing, 2 separate gets is way faster than using a map-reduce link-walk, which is disappointing :( I'm also testing on a one node cluster, and my bucket has a N/R/W=1. I was thinking that the reduction in networ

Re: Speed of linkwalking

Re: Speed of linkwalking
