Microsoft also announced today that SQL Server StreamInsight will ship as a component of SQL Server 2008 R2, and the CTP is available to MSDN and TechNet subscribers for download today. According to Microsoft’s Data Platform Insider blog, "StreamInsight will bring a low-latency complex event processing (CEP) platform to SQL Server, and will enable organizations to derive insights from streaming data in near real-time in scenarios such as web analytics, algorithmic trading and industrial process control." The StreamInsight CTP will be available to the public tomorrow, August 19th.
