Questions

  1. what would happen when we scale the function app, say if we have 2 instances of the function, will both the functions receive the messages (duplicates) from the queue ?

No. Each Function instance will get different messages. Essentially the messages are fetched in GET mode (i.e. they are dequeued) and if a message is dequeued by one Function instance, it will become invisible to other Function instance for a certain amount of time.
