I have a Function App, and sometimes, I notice that a Function Api(HTTP trigger) takes longer to respond. I belive this is due to the cold start limation.

Within my Function App, I have a function which is a timer triggered for every minute.

Due to function app being triggered every 1 minute, should the cold start limation still effect my Function App?

Thanks

When using the consumption plan, container resources are deallocated after roughly 20 minutes of inactivity, meaning that the next invocation will result in a cold start - source. So you shouldn't have sequential cold starts if you're triggering the same function app every minute.

Additionally, cold starts can still occur due to auto-scaling to handle capacity when creating a new container instance.

However, if you choose the premium plan, function apps are running continuously, or nearly continuously, avoiding cold starts with perpetually warm instances.
