Consumption plan scalability RRS feed

  • Question

  • Hi,

    We have function app that is triggered by event hub and we have quite massive amount of events (10 event hub throughput units). I am wondering how much function can scale. Somewhere I was reading that it can have only 10 machines running the function. Is that true?

  • Here's an SO response that may help shed some light on how Azure Function scales instances of your Function App containing your EventHub-Triggered Function.

    As for the question of how many instances can your Function App scale out to, I just want to clarify that under the default scenario where you can have a range of between 2-32 partitions.  As such, even if Azure Functions scaled out your Function App to 33 instances, only N instances where N=(number of partitions) can process the messages from your EventHub.
