StreamInsight Goes Public!
During the past few years we have heard from some of you on the need for incorporating “events” and “event streams” into your applications. In our conversations with all of you it emerged that some of you looked upon these applications as “Complex Event Processing (CEP) Applications” while some of you simply referred to them as low latency monitoring applications. These applications were referred to by different names in different domains ranging from manufacturing, utilities, oil & gas, financial services and IT monitoring to web analytics. Still, they all shared some common characteristics – the need to process large volumes of data in the form of event streams with minimal latency. In some applications the emphasis was on the ability to process events with very rich payloads (complex events) and in others the emphasis was on the ability to compute with minimum latency over very large event rates.
The key characteristics that emerged in all these cases was the necessity to have a rich model for expressing queries and an implementation of that query model that will facilitate incremental computation to incorporate newly arriving events into the query results with minimal latency. Both of these are key characteristics to fulfill the needs of the rich applications that address the business needs.
In conjunction with the database research team we worked on extending the relational algebra to incorporate the extensions needed for processing event streams and developed an efficient implementation for it. Microsoft SQL Server StreamInsight is the result of these efforts. In order to ensure a very good developer experience we focused on integrating it with features offered in our development environment – a LINQ provider for writing the queries and an event flow debugger.
Some of the offerings that we have in this CTP are in the alpha stages while others are in internal production employment. We believe that we have reached a juncture where it would be extremely important for us to share with you what we have along with our plans for the future and solicit your feedback. We value your feedback and look forward to working with all of you to develop the product that can address your needs.
Please download and try the CTP and give us your feedback. The best way to communicate your feedback is to report any bugs or feature requests at SQL Server Connect. Furthermore, the StreamInsight Forum is closely monitored by the development team and provides you with a basic level of support
