Please note that best practice is to avoid long running functions as explained here. https://learn.microsoft.com/en-us/azure/azure-functions/performance-reliability#avoid-long-running-functions

Hope this helps.

@Ash G so does this mean if i use premium plan then there will not be any limitation and the function can run forever?

That is correct, but as mentioned, it is not recommended. Also note the limitation mentioned here from the same link above:

If this situation applies to you, consider the two solutions mentioned in the article. The article has links explaining how to configure these solutions.

john john Thanks for posting your question. The limitation described above is for HTTP triggered Azure Functions that use Azure Load Balancer in the underlying infrastructure, which has a default timeout (240 seconds on Linux App; 230 seconds on Windows app). Hence, regardless of consumption or Premium plan, the request will time out and this is described in detail in Q&A thread: HTTPTrigger Response Timeout and doc: Why does my request time out after 230 seconds? We recommend using Durable Functions Async pattern for long running tasks in such scenarios.

However, for other trigger functions, there is no maximum time limit as discussed above. I hope this helps with your question and let us know for any other.
