To leverage In-Memory OLTP in your database, you use one or more of the following types of objects:Īre used for storing user data. In addition, In-Memory OLTP works with all high availability and disaster recovery capabilities of SQL Server, like AlwaysOn, backup/restore, etc. If there is a failure at any time after the transaction commits, your data is there when the database comes back online. By default, all transactions are fully durable, meaning that you have the same durability guarantees you get for any other table in SQL Server: as part of transaction commit, all changes are written to the transaction log on disk. Now, just because data lives in-memory does not mean you lose it when there is a failure. Data storage, access, and processing algorithms were redesigned from the ground up to take advantage of the latest enhancements in in-memory and high concurrency computing. Now, where does this performance gain come from? In essence, In-Memory OLTP improves performance of transaction processing by making data access and transaction execution more efficient, and by removing lock and latch contention between concurrently executing transactions: it is not fast because itĪround the data being in-memory.

With a single machine running SQL Server 2016, leveraging In-Memory OLTP. In-Memory OLTP can provide great performance gains, for the right workloads. We conclude with a sample script illustrating the In-Memory OLTP objects, and some pointers to get started. We go on to describe the scenarios for which you’d want to consider In-Memory OLTP. We then describe the resource/memory limitations in Express and Standard Edition.

In this blog post we recap what the technology is. One of the outcomes is that In-Memory OLTP (aka Hekaton), the premier performance technology for transaction processing, data ingestion, data load, and transient data scenarios, is now available in SQL Server Standard Edition and Express Edition, as long as you have SQL Server 2016 SP1. With SP1 we made a push to bring a consistent programming surface area across all editions of SQL Server. The release of Service Pack 1 for SQL Server 2016.
