Azure Functions Isolated Process with AzureAppConfiguration causing throttling

I've also noticed that in the examples given in the documentation the code looks like this:

.ConfigureAppConfiguration(builder =>
{
	// Omitted the code added in the previous step.
	// ... ...
})
.ConfigureServices(services =>
{
	// Make Azure App Configuration services available through dependency injection.
	services.AddAzureAppConfiguration();
})
.ConfigureFunctionsWorkerDefaults(app =>
{
	// Use Azure App Configuration middleware for data refresh.
	app.UseAzureAppConfiguration();
})

But in our version we have it like this:

.ConfigureFunctionWorkerDefaults()
.ConfigureAppConfiguration(builder =>
{	
	// Omitted the code added in the previous step.	
	// ... ...
	builder.AddAzureAppConfiguration();
}).ConfigureServices(services =>{	
	// Make Azure App Configuration services available through dependency injection.
	
})

I've removed a lot of the not necessary bits from the example, so hopefully it still makes sense. I don't think it should make a difference if we say there is no app configuration middleware or services injected.

@MuthuKumaranMurugaachari-MSFT Thanks for your response, ideally we wouldn't require more than 1000 requests per day as we're not particularly interested in refreshing the config that often. The problem we seem to be having is when running Azure Functions in Isolated mode on a consumption plan we end up with whenever the cold start triggers, it's reloading the Azure App Config settings and this cold start happens reasonably often for us.

I was wondering if there is a good way to cache this maybe?

Thomas Baxendale Got it, and in such cases (cold start triggers), Azure App Configuration will be reloaded and there is no way to cache that (similar answer shared by App Configuration PG). So, you would need to consider Standard tier for Azure App Configuration to avoid throttling errors or for performance increase, (avoiding cold start) checkout dedicated plans. Both involves additional cost and IMO it makes sense to go with former option considering the cost.

Perfect, that pretty much answers everything I needed.

Thanks @MuthuKumaranMurugaachari-MSFT 😊
