Abstract
A non-transitory computer-readable storage medium stores a data stream processing program that causes a computer to execute a process. The process includes extracting a relationship between properties included in events in a data stream from the data stream itself, definitions of queries for processing the data stream, or both of the data stream and the definitions of the queries; specifying a common partitioning key common to a subset of the queries to be grouped into a partitioning group based on partitioning keys in the definitions of the queries, the relationship between the properties, and a probability of the relationship; and assigning the subset of the queries belonging to the partitioning group to each of parallel nodes provided for parallel distributed processing based on the specified common partitioning key.
