STREAM DATA SYSTEM, STREAM DATA PROCESSING METHOD AND STREAM DATA PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a stream data processing system having scale out characteristics in combining processing of stream data to ensure high availability.

SOLUTION: The stream data processing system 1 includes one or more filter processors 10 with the same function. An information management device 30 of the stream data processing system 1 receives information source position information of data added to a corresponding data storage device 20 from data storage devices 20. Next, the filter processors 10 respectively inquire the information source position information from the information management device 30 to know a reference destination of the data to be combined with data received by the filter processors themselves. The filter processors receives data existing at the reference destination and combine the data with data received by the filter processors themselves. Each filter processor 10 performs such processing, and a reference device 60A receives combination processing results by each filter processor 10 and arranges the combination processing results.
