    You could modify the logic so that after completion of 'node A', a simple text file was written to signal that the node had completed its execution.

    Similarly, for 'node B' after it had completed it's execution the text file could be written to the file system.

    A Generate Data node can be configured to check for the existence of the semaphore file. If it does not exist the node waits for it to be present. If the file is present the node generates an output record and deletes the semaphore file.
