Azure-docs: Understanding Azure function app scaling with timetrigger and servicebus trigger.

[proguru]

Lets say, my function app is in a consumption hosting plan and I have 2 functions within it - a time trigger function that is triggered every 2 minutes (* */2 * * * *) and a service bus triggered function.
Now due to the number of messages in my subscription the consumption plan scales the function app to 10 instances and at the same time the the timer trigger event is raised. Now since the function app has scaled to 10 instances will all 10 of the timer triggered functions execute ?

@proguru Thanks for the question!

Even if the function app scales out, only one instance is triggered by the timer. This is also covered in its docs.
