In-Memory OLTP Internals

  • Dmitri Korotkevitch


Hekaton was the code name of an In-Memory OLTP Engine introduced in SQL Server 2014. It is an Enterprise Edition feature, and it is available only in the 64-bit version of SQL Server. Hekaton is Greek for one hundred, which was the target performance-improvement goal of the project. Even though this goal has yet to be achieved, it is not uncommon to see a 10X–40X system-throughput increase when In-Memory OLTP is used.
