Your cloud application uses Azure App Configuration to manage application settings and feature flags. The application needs to detect changes to configuration values and feature flags in near real-time without polling the configuration store continuously, which would consume too many requests. How should you implement this dynamic configuration refresh?

Question

Sunny · Accepted Answer

Configure the application to use push-based refresh by integrating Azure App Configuration with Azure Event Grid and a webhook or Service Bus queue.. Azure App Configuration supports dynamic configuration refresh using either a push-based or pull-based model. For near-real-time updates without heavy polling, the push-based model uses Azure Event Grid to listen for configuration changes and push notifications to a webhook, Azure Function, or Service Bus queue, which then triggers the application's configuration provider to refresh.
