Stream data processing system, stream data flow control program and stream data processing method

摘要

It is an object of the present invention is controlling the flow rate of the data to predict the amount of output data of the stream data processing system, and input to the stream data processing system. In the present invention, the processing result transmission unit which transmits to the receiver computer results and query information storage unit for receiving a query, and the stream data processing unit for processing stream data by query has been received, the result of processing a query, the computer, stream Queries and acquisition unit and a data transmitting unit that transmits the stream data to the data processing unit, acquires the queries stored in the query information storage unit, the processing result transmission unit transmits to the result receiving computer by analyzing the query by comparing the query analyzing unit for calculating a predicted value of the amount of data to, and the threshold set in advance the prediction value, if the predicted value exceeds the threshold value, the data transmission unit transmits to the stream data processing unit I have, a flow controller for regulating the stream data.
