It has happened: SQL Server 2008 R2 has RTM'd yesterday! Microsoft’s information platform vision provides enterprises with a “complete approach” to managing information assets, enabling all businesses to gain strategic value from information from the desktop to the datacenter to the cloud. And StreamInsight V1 is one essential piece in this spectrum. After more than a year of blood, sweat, tears, and insane amounts of coffee we are proud to release the first version of our Complex Event Processing Framework.

Those of you who have been following our Community Technology Previews (CTPs) throughout last year have already had the possibility to familiarize themselves with the product. Early feedback was not only incredibly positive, but also very constructive and strongly influenced the final feature set. Four notable increments over our last public CTP are:

  • Count windows

  • Non-occurrence detection (Anti-Join)

  • Dynamic query composition at runtime

  • Synchronize time across input streams

Additionally, many smaller issues and bugs were addressed. A few APIs slightly changed with respect to the November CTP, but porting your application to RTM should not require a lot of effort.

Here are the (english) bits - choosing the evaluation license during setup lets you already play with this version. Before you install, make sure to uninstall any previous CTP version:

StreamInsight X86
StreamInsight X64

Within a few days, we will update our product page and add download links and instructions there as well.

    Where can we find some details on the CTP increments?

    Hi Roman and Torsten and Beysim,

    Congrats, and it’s great to see that you have released your hard work. I am not involved in CEP right now, but I am watching your efforts very closely.

    I have installed StreamInsight RTM and I am trying to run some of the Demos from SQL Server 2008 R2 Update for Developers Training Kit (April 2010 Update).

    It seems that the Microsoft.ComplexEventProcessing.Adapters.Observable namespace is not there any more (changed since the November CTP?).

    Any idea what happened? Are there any examples that work with RTM ?



  5. Yannis,

    The Training Kit was built against the November CTP of StreamInsight. The RTM version is shipping without the Observable feature, but it will be added back in an upcoming release.

    We are currently in the process of publishing the RTM samples, and will announce that here as soon as possible.

    Any words on getting the Observable feature? It's been 7 months that you posted above. The examples under streaminsightexample.codeplex.com doesn't work.



  7. Rachit,

    The Observable integration has been introduced last October with our 1.1 release, see here: blogs.msdn.com/…/releasing-streaminsight-v1-1.aspx

    Several recent blog postings have talked about it, like these two:



    With StreamInsight 1.1 installed, the samples on CodePlex should work – if not, please let us know what the exact error is!
