Is there a way to cancel a running MR script?

undeploy the script or inactivate it. It will not stop rigth away, you will need to wait some time.

I think the wait is basically until the currently executing stage(s) complete.

👍🏻 Thanks

IIRC, experimenting with this it waited (in my case) until the currently executing

map()

returned - it looks like NS checked that the script was active before it invoked the next

map()

call
