In a computer system, plural computers perform an analysis processing of a data set including plural data configured by a key and a data value. Each of the computers retains division information which manages a division position key indicating a division position of a division area obtained by dividing the data set for every predetermined key range, for every data set, all division position keys included in the division information of each of the data sets are the same. When a new data set is stored in the file system, the computer system determines whether there is a target area which is the division area having a data size larger than a predetermined threshold value, based on a data size of each of the division areas after storing the new data set, and if the target area is present, it divides the target area into plural new division areas. |
