At first sight, this looks like a competitor to json based data stores such as mongodb. However, it looks like json is just a line format and you still need to write T-SQL.
Well Entity Framework 7 is meant to have support for non-relational data sources [1] so ... at some point you probably won't have to write Transact-SQL for dealing with JSON data in your cookie-cutter OLAP applications written with .NET.
