Abort only a child pipeline

[Mayank Bhagya]

Hello,

Is there any way in which I can abort only a child pipeline without aborting the entire thing upto its root?

Thanks

No, the goal of abort is to fully abort the entire hierarchy. If you want to do retries like that you'll need to use the return value of a pipeline to cause retries at a higher level. That's much more "functional" looking and may require a pattern that looks like recursion.

Is the question regarding the Python or the Java Pipeline implementation.

If for Python then you have Brett's answer. If for Java, you can still

apply the same concept though you could also use the exception handling mechanism.

Thanks Brett. I wasn't trying retries.

I was running a batch-like job where child pipelines represent a single unit of work.

So, my parent pipeline spawned about 1000 child pipelines, one 'after' the other.

So if 795th job fails, I still wanted the remaining jobs to finish rather than aborting the entire thing and preventing the subsequent pipelines from running.

Thanks.

Hello Arie. Yes, this was regarding python.
