Abstract: The data processing management system includes a queue deployment system that deploys a queue with a processing description of stream processing having a branch instruction being an input. The queue deployment system designates processing to be preferentially executed for the processing description, measures throughputs in respective processing after the branch instruction, and obtains branch proportions that at which the respective processing after the branch instruction is executed. The queue deployment system then computes deployment costs in a case of deploying a queue between the branch instruction and the respective processing after the branch instruction, for combinations of the respective processing after the branch instruction using the throughputs and the branch proportions, and outputs a queue deployment pattern for preventing a decrease in a throughput of the processing to be preferentially executed among the respective processing after the branch instruction.
