<p>PROBLEM TO BE SOLVED: To provide a stream data processing method using a recursive query of graph data.SOLUTION: A stream data processing computer includes a query execution part that receives an input stream to be stream data, manages execution order of an operation part for executing queries and outputs an output stream to be stream data, and a memory that includes a temporary storage part for storing data generated when the queries are executed. The operation part includes a plurality of static recursive execution parts, a determination operation part and a dynamic recursive execution part. The plurality of static recursive execution parts perform static recurve execution of the queries by the recursive number of times. The determination operation part determines whether or not a previously set condition is satisfied after the static recursive execution of the queries is performed by the recursive number of times. The dynamic recursive execution part, when the previously set condition is not satisfied, continues the execution of the queries by dynamic recursive execution.</p> |
