Does riak support range queries?

[smn]

It does on secondary indexes http://wiki.basho.com/Secondary-Indexes.html

I should mention that 2I performance may be a little slow, depending on what kind of indices and queries you need. It's not hard to try it out and benchmark, though.

Yes, it does range queries based on key, if the key follows a defined format.

It also has secondary indexes.
