Exercise - Publish and receive events with Azure Event Grid
I content moderation systems generate a high volume of events as they classify and review submissions. Azure Event Grid provides the routing layer that directs these events to the right downstream consumers based on event type, so each handler receives only the events it needs without polling or manual filtering.
In this exercise, you deploy an Event Grid Namespace with a namespace topic and filtered event subscriptions, then build a Python Flask application that publishes content moderation events and receives them using pull delivery. Event Grid subscriptions route flagged content, approved content, and all events to separate subscriptions so you can observe how filtering works in practice. You also use the receive, acknowledge, and reject operations that pull delivery provides to control how your application processes events.
Tasks performed in this exercise:
- Download the project starter files
- Deploy an Event Grid Namespace with a namespace topic
- Create event subscriptions with type filters
- Add code to the starter files to complete the app
- Run the app to publish, receive, and process moderation events
This exercise takes approximately 30 minutes to complete.
