The codename for a Microsoft project that will provide support for mixing in-memory database tables with more traditional on-disk tables in the same database. These hybrid databases will be able to dynamically handle both in-memory and on-disk storage in the same database for optimal performance and reliability.
Project Hekaton's in-memory database technology will be featured in the next major release of Microsoft SQL Server, which is expected to officially debut sometime in 2015. The project gets its codename from the Greek word for 100 times, which is the peak performance improvement goal the company has set for Hekaton.
Project Hekaton will enable Microsoft to compete in the in-memory database market with products like Oracle Database's Exadata and Exalytics appliance options and SAP Hana.
