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

Perfmon counters


SQL Server also provides perfmon counters for the In-Memory OLTP engine. However, perfmon is a much older technology than Extended Events and has certain limitations that prevent it from exposing all the details that Extended Events can. Be as it may, it is still possible to collect certain information on the In-Memory OLTP engine.

A T-SQL query to return a list of the perfmon counters that are available for the In-Memory OLTP engine would be:

SELECT object_name, 
    counter_name 
FROM sys.dm_os_performance_counters 
WHERE object_name LIKE '%XTP%'; 

Assistance in migrating to In-memory OLTP

Now that we have explored the possibilities that memory-optimized tables offer, it would be fantastic to be able to somehow evaluate our existing databases. Ideally, this evaluation would show how many tables or stored procedures could potentially be converted from traditional disk-based objects into ultra-fast memory-optimized objects.

Luckily for us, Microsoft has also...
