Dynamic stream rate of continuous queries, real-time deadline and important value in high critical data stream application is considered in this paper. Firstly, current time stamp, deadline and value are all taken into account in defining a new priority of query operator here. Based on this priority, a value and relative deadline jointly based query scheduling algorithm in different stream rate is proposes. The experimental results indicate that the algorithm raises the hit value radio (HVR) and the success ratio continuous query scheduling.
