Is it possible to execute pentaho step in sequence?

Question

I have a pentaho transformation which is consist of, for example, 10 steps. I want to start this job for N input parameters but not in parallel, each job evaluation should start after previous transformation are fully completed(process done in transaction and commited or rollbacked). Is it possible with Pentaho?

Answer 1

You can add 'Block this step until steps finish' from Flow to your transformation. Or you can mix 'Wait for SQL' component from Utility with loop on your job.

Answer 2

Maybe you must do it using jobs instead of transformations. Jobs only run on sequence while transformations run on parallel. (Truly, a transformation has a initialize phase whose run is in parallel and then the flow runs sequentially).

If you can't use jobs, you always can do what Matusz said.
