    Default Help with conditional execution in jobs

    I'm trying to create a job where a transformation gets executed only if all of three previous steps finish correctly. I'm guessing you can handle that with an "evaluation" step, but I'm not sure what the evaluation should check.

    Any help will be really appreciated.

    If you want to stop processing as soon as one transformation "errors":
    - put a start job entry and your three transformations in sequence
    - Use green hops to connect them and you have your execution that stops when a transformation fails.

    Indeed, however I was hoping on executing transformations in parallel. Based on your reply I assume that's not how it works, am I right?

    Thank you.

    Default parallel?

    I don't think you can design your job to run transformations in parallel. This can be done using scheduler and calling each transformation separately. Unfortunately pentaho lacks scheduler which limits it's scalability
    I hope the scheduler is something developer team is working on. I heard that some version might be available before the end of the year.

    No parallel runs in jobs for the moment. You want parallel runs you have to split up your job and run the resulting parts via a scheduler.

    Not having an own scheduler (or integrating with one) doesn't limit scalability, it just requires some command line fidgiting which could possibly be avoided
