Thread: "Job Entry" step?

    Default "Job Entry" step?

    A few days ago I had this idea: perhaps we could create a step that executes a job entry.

    The parameters for the job entry could be variables that are set using input fields.
    So the input is a field-to-variable mapping.

    The output could be generic: the result, the result rows, the result files, etc.
    Anything you want from the Result object really.

    For example, you could be very flexible as far as the FTP job entry is concerned.
    You could very easily loop over a number of FTP sites and get back the list of transferred files as a result to the next step that can automatically read them say with CSV Input.

    Thoughts?

    All the best,
    Matt

    Default Re: "Job Entry" step?

    So this would mean that transformations could fire off jobs instead of only
    jobs starting sub-jobs?

    I would think this would be okay. Your job entry step may be in the middle
    of a transformation and other steps would depend on the result. Therefore,
    I guess it might imply that you pause execution at that step while you
    execute a new job/transform tree and wait for the results to bubble back
    up. How would you get the results back up the tree?
