Microsoft has RTM'd SQL Server 2014, which includes a new in-memory OLTP engine built jointly by Microsoft Research and the SQL Server team.



From All About Microsoft:

The newest version of SQL Server's biggest new feature is its built-in in-memory online transaction processing (OLTP) capability, which Microsoft has said can improve database performance up to 30 times (not 30 percent -- 30 times) without any code changes to existing applications or hardware. The in-memory OLTP engine is codenamed "Hekaton." The Hekaton capabilities are designed to complement the in-memory data-warehousing and business-intelligence capabilities that are already in SQL Server.

Hekaton was developed jointly by members of Microsoft's SQL Server team, in conjunction with Microsoft Research's Database Group over the past five years.
