Configuration of asynchronous message processing in dataflow networks

Managing a concurrency based system. A method includes determining a defined number of concurrent operations for a concurrency based management system. An operation queue is accessed. The operation queue stores or has therein zero or more asynchronous operations. An asynchronous operation is an operation that returns an object representing the asynchronous completion of the operation. The method further includes, as long as the queue is not empty, scheduling asynchronous operations from the queue until a number of asynchronous operations equal to the defined number has been reached.
