Ruminations of J.net idle rants and ramblings of a code monkey

When StreamInsight 2.1 came out, the Big New Thing for the release was the new model for data ingress and egress – sources and sinks. Based on standard interfaces like IObservable and IObserver and the Reactive Extensions, it makes getting data into and out of StreamInsight a whole lot easier. The p... [More]

I got this question at Sql Saturday BI Edition in Dallas not too long ago. My answer was the usual one … “Well, you write an input adapter or (in 2.1) a source in .NET …”.  “Yes, I know that,” the asker replied, “but where does it come from?” &l... [More]

Houston TechFest is tomorrow at the Reliant Center. And, of course, I will be speaking. This year, I am doing two sessions: Back to Basics: .NET Essentials You May Have Forgotten (3:40 PM – 4:40 PM) Now that the .NET Framework has been out for 10 years and so many tools are available to make...

In this case, I’ll be talking about StreamInsight 2.1 and the new adapter model based on Observables and the Reactive Extensions. I hope to see you there! In other no... [More]

This is one of those things that I’ve always had some manner of difficulty with as I move between computers writing StreamInsight code. You see, I have … let’s see … four different computers that I write code on and I will move projects between them. (Yes, I do have an instance of TFS running at hom... [More]

This is one of the things that I’ve found a little frustrating when installing StreamInsight … entering the PID (product ID). You see, I have an MSDN subscription (every developer should!) and, therefore, I have versions of all of the Sql Server editions … including Sql Server Developer Edition, whi... [More]

I am honored and not a little happy to have been recognized by Microsoft as a Most Valuable Professional (MVP) for SQL Server in recognition of my involvement on the forums, this blog and my expertise in StreamInsight. I got the official notification on Sunday … April Fool’s Day. But it was no joke.... [More]

Way back in 2010, Mark Simms posted a blog entry called StreamInsight: Understanding dynamic query composition where he detailed how you can use dynamic query composition (DQC) to prevent multiple instantiation of your adapters. And yes, it is important … very important … for this reason but there i... [More]

This came up recently on the forums and I’ve been meaning to blog about it and, finally, I’m doing it. Before I get going let me just say the following things: There are a couple of ways to work around the bug. It is fixed in StreamInsight 2.0. It does not apply to StreamInsight 1.1. Only... [More]
