Azure Function Deployment while Running

Let's say I have an Azure Function named func running. In the middle of func running, I deploy some new changes to the func. Will func finish the current run and then start with the new changes or will the current run just end?

Maybe this can help you:

The reliable execution model of Durable Functions requires that orchestrations be deterministic, which creates an additional challenge to consider when you deploy updates. When a deployment contains changes to activity function signatures or orchestrator logic, in-flight orchestration instances fail. This situation is especially a problem for instances of long-running orchestrations, which might represent hours or days of work. To prevent these failures from happening, you have two options:

  • Delay your deployment until all running orchestration instances have completed.

  • Make sure that any running orchestration instances use the existing versions of your functions.
