Optimization of Query Plan in Data Stream System

摘要：

According to the data characteristics, the data arrival rate,the selectivity and the correlation among the query operations in data stream, a core algorithm called CSOQP (Combination Section Optimization Query Plan) is proposed.By the block size of data stream, CSOQP can release the contradiction between the cost of the scheduling processing and speed of the query processing. With a proper parameter,CSOQP can easily cope with the fluctuating problem in selection of query plan and strongly optimize the query plan in space and time.
