RETRIEVAL REQUEST CONTROL DEVICE, RETRIEVAL REQUEST CONTROL PROGRAM AND RETRIEVAL REQUEST CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To improve the efficiency of data retrieval when adopting index technology for high-traffic technology.SOLUTION: A retrieval request control device 1 comprises: a retrieval request set division unit 11 for dividing a retrieval request set including a plurality of retrieval requests acquired in a predetermined period into a plurality of subsets based on the degree of overlapping of data retrieved by each retrieval request; an average response calculation unit 12 for calculating an average response of retrieval requests included in the retrieval request set according to the processing order of the plurality of subsets divided by the retrieval request set division unit 11; and a retrieval processing unit 13 for, regarding a plurality of subsets having the quickest average response calculated by the average response calculation unit 12, performing the batch processing of retrieval requests included in the subsets according to the processing order.
