Explanation

The Azure Cosmos DB change feed publishes the full, current state of a document after it has been created or modified - meaning it delivers all properties of the updated item. The change feed does not deliver deltas (only changed properties), it does not include the original pre-change version of the item, and it does not limit the payload to just system or partition key properties. Functions triggered by the change feed receive complete documents, which is why the change feed is well-suited for event-driven scenarios where downstream consumers need the full item context.
