Currently in documentation on multi-geo dataflows are listed as non-supported feature:
Without any additional information on what is it that is not supported...
However when I configure and new capacity node and assign it to a different geography I notice a few curious things:
1. Dataflows Workload can not be disabled ( the switch off is greyed out) and limiting max memory for it is not possible(5% is min)
2. I am able to create dataflows in workspaces assigned to this new capacity just fine and even create reports based on dataflows stored in workspaces assigned to a different capacity
Can anyone with experience in multi-geo capacity configuration chime in and provide some clarifications here?
I would suggest you create a support ticket here.
