Document directory Preparations Basic Query Query Mode Official Guide Streaminsight is a new module in SQL Server 2008 R2. It provides the complex event processing (CEP, complex event processing) function. That is, it provides nearly zero-latency continuous processing for infinite event sequences from multiple data sources. Streaminsight is a temporary query processing engine that allows applications to query and process events within a time win
