Riak Time-Series API

Goal

The goal of a time-series API on Riak is to provide a reusable solution to a common problem faced by customers. The problem at a high level is that there is currently no built-in way to fetch more than one Riak object given start and end parameters.

Minimum Features

The API should at minimum expose a way to easily store individual events as well as a way to query for multiple events given start and end times.
