Are you trying to figure out whether StreamInsight might be something you could use, but you’re having trouble sifting through all the programming jargon that’s used to describe it? StreamInsight is, ultimately, a set of programming tools, and at some...

If you're just beginning to get familiar with StreamInsight, you may be looking for a way to get started. What are the basics? How can I get my first StreamInsight application running so I can see how it works? Where is the 'front door' that will get...

Until now, we've released StreamInsight through the Microsoft Download Center, and also released it out through Microsoft Update. Going forward, we will only release new StreamInsight versions through the Microsoft Download Center and only use MU to release...

In the previous blog posting, we showed how to construct and deploy query fragments to a StreamInsight server, and how to re-use them later. In today’s posting we’ll integrate this pattern into a method of dynamically composing a new query...

The changes in our APIs enable a set of scenarios that were either not possible before or could only be achieved through workarounds. One such use case that people ask about frequently is the ability to parameterize a query and instantiate it with different...

Back in 2010 we released the first version of an educational guide to StreamInsight Queries to help developers mind shift into the new paradigm. With the release of StreamInsight 2.1 and introducing the New Programming Model, we thought this was the right...

I tend to partition StreamInsight operators into three classes: the basic “temporal/relational” operators; the “time travel” operators, and; the “elephant” operators. The basic operators illustrate the rules. The time travel operators bend the rules....

Someone recently called LINQ “magic” in my hearing. I leapt to LINQ’s defense immediately. Turns out some people don’t realize “magic” is can be a pejorative term. I thought LINQ needed demystification. Here’s your best demystification resource: http...

At first glance, hopping windows seem fairly innocuous and obvious. They organize events into windows with a simple periodic definition: the windows have some duration d (e.g. a window covers 5 second time intervals), an interval or period p (e.g. a new...

In previous versions of StreamInsight (1.0 through 2.0), CepStream<> represents temporal streams of many varieties: Streams with ‘open’ inputs (e.g., those defined and composed over CepStream<T>.Create(string streamName)...

We are announcing the availability of the LinqPad driver for StreamInsight 2.1 . The purpose of this blog post is to offer a quick introduction into the new features that we added to the StreamInsight LinqPad driver. We’ll show you how to connect...

The wait is over—we are pleased to announce the release of StreamInsight 2.1. Since the release of version 1.2, we have heard your feedbacks and suggestions and based on that we have come up with a whole new set of features. Here are some of the...

Fresh from the press – The March 2012 issue of MSDN Magazine features an article about the Internet of Things. It discusses in depth how you can use StreamInsight to process all the data that is continuously produced in typical Internet of Things scenarios...

Hello Folks, With StreamInsight 2.0 barely out the door, it may seem soon to start talking about the next version, but the team has been busy adding features and trying to keep to our usual 6-8 month release cycle. And with 2.1 shaping up to be a pretty...

This has come up several times in the wake of our 2.0 release: The new LINQPad driver supporting StreamInsight 2.0 is now live! You can download it as usual through the LINQPad UI: There are separate versions of the driver only because assembly references...

A couple of days ago, we released a new StreamInsight white paper/case study on TechNet and MSDN. The paper is joint work with ICONICS and discusses how ICONICS is using StreamInsight technology for its Energy AnalytiX® solution. The paper is available...

The StreamInsight Team is proud to announce the release of StreamInsight V2.0! This is the version that ships with SQL 2012, and as such it has been available through Connect to SQL CTP customers already since December. As part of the SQL 2012 launch...

Time for a life sign from our Team Blog, and a very exciting one: Richard Seroter , Principal Software Architect and Microsoft MVP, has put together a comprehensive Pluralsight course on StreamInsight . Richard has been a great StreamInsight advocate...

One of our goals in version 1.2 was to improve the administrative surface of StreamInsight. The newly introduced performance counters enable you to retrieve diagnostic information and monitor health and performance in real-time. Rafael has put together...

Who knows what window output policies in StreamInsight LINQ are? Anyone? Well, you have been using them whenever you have used a window. Output policies specify the timestamps of the result of the aggregation that happens on the window. Even if you didn’t...

StreamInsight LINQ is powerful and expressive. At the same time, the learning curve for a new user can be steep, because the query operators work on a semantically basic level. This means that complex use cases need to be build bottom up, composing the...

Over at his blog , Isaac Kunen posts : One of the big features in the new version is resiliency, which helps you build highly available systems that use StreamInsight. This post gives a high-level, no-code overview of what this functionality does and...

In a previous posting , we introduced nested types as one of the new features in StreamInsight V1.2. The second improvement in the type system represents the other end of the complexity spectrum, namely the ability to use "primitive" event types, without...

One of the focus areas for us in V1.2 was the LINQ surface of StreamInsight. We have straightened out many of the kinks people complained about in previous versions and have added new features. Too many improvements for a single blog post, so today we’ll...

With the release of StreamInsight V1.2 we also updated our LINQPad driver. It is now aware of StreamInsight versions, so that a sample can fail gracefully if the required library version is not found. You can install the new driver (of update your...
