hi team, the documentation states that subworkflows execute within context of the parent workflows (here). What are the implications of that?

they will run on the same propeller, they have the same settings like project/domain/service_accounts and other settings like interruptible

the doc also says they'll have same parallelism, but isn't parallelism configured at task level?

no parallelism (node parallelism) is at the workflow level

are you referring to max_parallelism arg of LaunchPlan?

yes

max_parallelism (Optional[int]) – Controls the maximum number of tasknodes that can be run in parallel for the entire workflow. This is useful to achieve fairness. Note: MapTasks are regarded as one unit, and parallelism/concurrency of MapTasks is independent from this.

do I read this right that it doesn't apply to maptasks? What about spark?

yes

got it, thanks
