StreamInsight 1.1 released

A new version of StreamInsight has just been released. The biggest news are support for the Reactive Framework in .NET 4.0, making it much easier to integrate with existing .NET applications, better performance and stability, especially for edge joins, and side-by-side installation with older versions.

Any of you who tested the StreamInsight CTPs may remember there was support for two interfaces, IObservable/IObserver. These were removed in the RTM but are now replaced by support for the .NET 4.0 IObservable and IEnumerable interfaces. These provide an alternative to develop adapters and can help simplify access to historical data.

I've started twittering

I've decided it's finally time for me to start twittering. I'm usually not the kind of guy who lags behind when new technologies come, but I must admit I thought it a bit overkill to have more than one place (my blog) to write. Now I have given in to the pressure... J

You'll find me on Twitter under the username @johanahlen. I will keep twittering about SQL Server, StreamInsight, Azure and Cloud technology, Business Intelligence and technology in general. So you'll probably keep hearing more from me there.
