SQL Server 2012 (“Denali”): Microsoft StreamInsight

Microsoft StreamInsight, first introduced in Microsoft SQL Server 2008 R2, is a way to effectively analyze large amounts of event data streaming in from multiple sources.  You can derive insights from critical information in near real-time.  StreamInsight is a platform for Complex Event Processing (CEP) giving you the ability to monitor, analyze, and act on data in motion and make informed decisions almost instantaneously.  Example application areas for CEP include financial applications, fraud detection, manufacturing, surveillance of internet traffic and real-time business intelligence.

Currently at version 1.2 of StreamInsight.  SQL Server 2012 will include version 2.0 of StreamInsight.

StreamInsight 2.0 requires Microsoft SQL Server 2012 Release Candidate 0 (RC 0) license and .NET Framework 4.0. It includes the following performance improvements along with few bug fixes.

Performance Improvements

The following issues that help improve performance of a StreamInsight application are fixed in this version.

  • Queries can deadlock when a join operator has input streams that originate from a common source.
  • The memory consumed by a StreamInsight application may grow infinitely when lifetime of the left-side reference stream overlaps with a right-side continuous real-time stream of a Left Anti Semi Join operator.
