Secondary indexing

In my application, I have a frequent need to store collections of data where I rarely access the items individually, but much more commonly in aggregate form. In principle, the mapreduce feature is well suited to this, but it must be fed a set of {bucket,key} pairs to consume, and maintaining these

This sure looks like a bug...?

I have an app using the protobuf API that's exhibiting some strange behaviour. I have a bucket with allow_mult = true, so when I perform a PUT I expect that if a matching key exists, a sibling will be created, and the response to the PUT should contain both the pre-existing value and the new value

When's the PBC API going to be brought up to snuff?

Hi, folks - I'm developing a rather performance-sensitive app against Riak, and while the PBC API has much better raw performance than the REST API, it is sufficiently crippled in numerous ways as to be of quite limited use. This is somewhat frustrating, as notionally simple operations such as a c
