摘要
A system and method for maintaining and updating a complex event processing system in response to real-world changes, to avoid non-optimal queries that can lead to poor performance and/or erroneous results. The knowledge model of the complex event processing system is monitored to identify elements that impact query optimization and additional knowledge elements that would impact query optimization if they were present. A watch model is constructed for the identified elements, and responses to monitor queries sent to the event processor are checked to determine if the system requires re-optimization. When monitor query responses indicate that the system requires re-optimization, the affected queries are re-optimized and redeployed automatically.
