FILTER PROCESSOR, DATA STORAGE DEVICE, SHARED INFORMATION MANAGEMENT DEVICE, FILTER PROCESSING METHOD AND FILTER PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent reduction of processing capability of the whole system even when receiving various stream data from an information source. SOLUTION: A filter processing means 10 (10A-10N) used for a stream data management system 1 receives queue state information showing a queue state in a data storage means 20 from each of the data storage means 20 storing the stream data. The filter processing means 10 selects the data storage means 20 that is an acquisition source of the stream data on the basis of the received queue state information. The filter processing means 10 acquires the stream data from the selected data storage means 20, and executes prescribed filter processing to the stream data. When the filter processing means 10 downloads file data from a shared information management means 30 and adds a filter processing function, the filter processing means 10 confirms to the shared information management means 30 whether a restart can be performed or not.
