How to use parallel insert in SQL Server 2016 to improve query performance

December 8, 2017 by


In the first part of this article, we will discuss about parallelism in the SQL Server Engine. Parallel processing is, simply put, dividing a big task into multiple processors. This model is meant to reduce processing time.

  • SQL Server can execute queries in parallel
  • SQL Server creates a path for every query. This path is execution plan
  • The SQL Server query optimizer creates execution plans
  • SQL Server query optimizer decides the most efficient way for create execution plan

Execution plans are the equivalent to highways and traffic signs of T-SQL queries. They tell us how a query is executed.

October 2, 2017 by

In an era of remote storage and retrieval of data, including the cloud, data security plays a vital role, especially since it’s vulnerable during the transit.

We have seen a noticeable surge in the technologies around protection and security of data from the world full of unsafe hands.

In-Memory OLTP Enhancements in SQL Server 2016

August 22, 2017 by

SQL Server In-Memory OLTP, also known as Hekaton when it was introduced in SQL Server 2014, provides us with the ability to move specific database tables and suitable stored procedures into memory and compile the stored procedures into native x86 code. As a result, you can easily query these database objects directly from memory with the best performance and the least possible data access latency. In addition to that, the SQL Server Engine will no longer use the old latching and locking mechanism to control the data access concurrency. Instead, a high performance row versioning mechanism will be used to control the concurrency. This optimistic concurrency mechanism is 5 times to 20 times faster than the normal disk-based processing, due to reading the data from the memory directly.
