        Note that returned publisher will be publishing entries from the invocation of the executor. Thus any subscription will not block the thread it was invoked on, unless explicitly configured to do so.

        Type Parameters:
        R - the returned value
        Parameters:
        segments - segments to parallelize across
        executor - the executor execute parallelized operations on
        publisherFunction - function that creates a different publisher for each segment
        Returns:
