As we all know, PostgreSQL claims to have implemented NoSQL functionality in their SQL database by playing games with JSON.
What you may not know is that pure-bred NoSQL databases have also started to get into the SQL world.

OpenRiak would like to present OpenRiak TS 3. TS (Time Series) inherits the rock steady fault tolerance of KV but is designed to give much faster access to groups of data by storing them closer together on disk for faster sequential retrieval. To allow for easier adoption, SQL functionality such as MEAN, MEDIAN, AVERAGE, as well as LIMIT and ORDER BY compliment the basic SELECT, INSERT, UPDATE and DELETE functions that everyone would expect as a minimum base to work with.
