Sorting used to be done through M/R queries. Does Riak perform a M/R sort on the results from each node from this release ? Just wondering how this sort is achieved and what it means for performance, if it is requested.

It does a merge sort, and I can't see that you can opt out of it: https://github.com/basho/riak_kv/blob/master/src/sms.erl

2i doesn't use mapreduce in normal operation.
