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

Management of in-memory objects


Managing memory-optimized tables is similar to disk-based tables. SQL Server Management Studio provides full syntax and GUI support for memory-optimized tables. There is a long list of Dynamic Management Objects (DMOs) that provide detailed insights into each aspect of the feature, but the legacy management objects such as sys.tables or sys.indexes have also received some updates to include pertinent memory-optimized information.

Dynamic management objects

The DMOs concerned with the In-Memory OLTP engine all have XTP (eXtreme Transaction Processing) in their name:

  • sys.dm_db_xtp_checkpoint

  • sys.dm_db_xtp_checkpoint_files

  • sys.dm_db_xtp_gc_cycles_stats

  • sys.dm_xtp_gc_stats

  • sys.dm_xtp_system_memory_consumers

  • sys.dm_xtp_threads

  • sys.dm_xtp_transaction_stats

  • sys.dm_db_xtp_index_stats

  • sys.dm_db_xtp_memory_consumers

  • sys.dm_db_xtp_object_stats

  • sys.dm_db_xtp_transactions

  • sys.dm_db_xtp_table_memory_stats
