Responding to events

The next step is to define an endpoint, which is the event handler that is responsible for processing an event. Currently, you can select quite a few handlers depending on how you plan on reacting to the event, as seen here:

You can also put filtering on your events. Filtering events from an Azure IoT hub can be a valuable tool for managing and processing IoT data efficiently. Here are some reasons why you might want to use filtering for IoT Hub events:

• Reducing data volume: IoT devices can generate a massive amount of data, and not all of it may be relevant to your specific use case. Filtering allows you to discard or route only the events that meet certain criteria, reducing the volume of data that needs to be processed and stored. This can help save on data storage costs and processing resources.
• Selective routing: Filtering enables you to route specific types of IoT events to different...
