Query Processing in In-Memory OLTP (Hekaton)
Application & Database Development
In-Memory OLTP (code name: Hekaton) is the most important new feature in SQL Server 2014, and this session will teach you how query processing and optimization work with this new database engine. After explaining the basics, we will discuss how the query optimizer is used in In-Memory OLTP by both natively compiled stored procedures and by traditional stored procedures accessing memory-optimized tables through the query interop functionality. We will also take a look at how the new hash and range indexes are used, as well as how their performance implications are also covered along with the process of translating the plan created by the query optimizer into C code. Finally, some limitations with the current release will also be explained.
