Overview of this book

Microsoft SQL Server 2016 is considered the biggest leap in the data platform history of the Microsoft, in the ongoing era of Big Data and data science. This book introduces you to the new features of SQL Server 2016 that will open a completely new set of possibilities for you as a developer. It prepares you for the more advanced topics by starting with a quick introduction to SQL Server 2016's new features and a recapitulation of the possibilities you may have already explored with previous versions of SQL Server. The next part introduces you to small delights in the Transact-SQL language and then switches to a completely new technology inside SQL Server - JSON support. We also take a look at the Stretch database, security enhancements, and temporal tables. The last chapters concentrate on implementing advanced topics, including Query Store, column store indexes, and In-Memory OLTP. You will finally be introduced to R and learn how to use the R language with Transact-SQL for data exploration and analysis. By the end of this book, you will have the required information to design efficient, high-performance database applications without any hassle.

In-Memory OLTP Improvements in SQL Server 2016

Summary


In this chapter, we took a look at the In-Memory OLTP engine as it was introduced in SQL Server 2014. Along the way, we investigated how the In-Memory OLTP differs from the traditional SQL Server storage engine with respect to the concurrency model. The main difference is the ability to allow multiple concurrent users to access the data structure without relying on the pessimistic concurrency model of using locking and latching to uphold data isolation within transactions.

We continued our journey by exploring what T-SQL constructs and data types the In-Memory OLTP engine can support the first version of the feature inside SQL Server 2014. At the same time, we were able to find out that although there are limitations, there is still a wide range of available data types and programming approaches that can be used immediately. Especially exciting is the fact that the T-SQL language receives (almost) transparent support for powerful new capabilities. Memory-optimized tables appear at...
