Abstract
A data processing method is executed by a computer to perform distributed processing of a first query and a second query. The data processing method includes calculating a first value indicating a dependency between a first partitioning key and a second partitioning key, the first partitioning key specifying a categorical attribute extracted from syntax of the first query, and the second partitioning key specifying a numerical attribute holding numerical values associated with the second query; generating a query group made of the first query and the second query based on the first value; and performing distributed processing of the first query and the second query based on the query group when executing the first query and the second query.
