Title: DATA PROCESSING SYSTEM AND DATA PROCESSING METHOD
Abstract:
[Problem] To provide a data processing system that can execute a parallel distributed process at a high speed. [Solution] The present invention configures a data processing system (100) provided with: a plurality of first server devices (130) that, in parallel, perform an analysis process comprising an extraction process for extracting columns and column values from data to be analyzed and an aggregation process for aggregating, with a key column as a key, data to be aggregated; and a second server device (140) for performing a process for determining the key column on the basis of the process results of a past analysis process, a process for producing key distribution information indicating the percentage of appearance of each column value in the key column, and a process for determining the plurality of first servers (130) to perform the aggregation process on the basis of the key distribution information. Also, the second server device (140) determines the plurality of first server devices (130) to perform the aggregation process by means of allocating data to be aggregated, which results from dividing the data to be analyzed into each column value of the key column, to the plurality of first server devices (130) in accordance with the percentage of appearance of the column values.
