When trying to start SQL Warehouse from my Azure pay-as-you-go subscription, I'm getting error about not enough vCPUs provisioned. Documentation says to increase quota at Azure portal - but it requires knowing type of vCPUs to provision. What type of CPUs should be provisioned? Is it EDSv4 family, or spot instances, or something else? What is the best way to see what clusters each t-shirt size of SQL Warehouse is using? Thank you.
