Azure-docs: Azure Functions Premium plan

Created on 19 Jan 2020  Â·  5Comments  Â·  Source: MicrosoftDocs/azure-docs

Reading this https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale#premium-plan it states

Unlimited execution duration

Even though the maximum timeout for premium plan is 60 minutes: https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale#service-limits

Isn't 60 minutes the correct value and not unlimited duration for premium plans?

Hi, we're adding more clear verbiage to that soon. For Premium we guarantee at least 60 minutes of execution time, but do not restrict you from running longer. I've personally tested 4 hour executions without any trouble.

We do restart your site every 4-6 weeks for platform updates, which require restarting all running workers. We'll wait up to 60 minutes before killing your process, so your execution time can be as long as 6 weeks or as short as 60 minutes depending on how lucky your timing is :)
