A salt-marsh nursery wants every insert and update on plant items, in modification order, without polling the Cosmos container. Which Cosmos mechanism should the developer use?
Select an answer to reveal the explanation.
Short Explanation
Stop ringing the greenhouse every minute asking “anything new?” The change feed is Cosmos’s built-in change log for inserts and updates in order. Event Grid and Event Hubs are Domain 5 messaging—not this Domain 2 notification skill.
Full Explanation
The Cosmos DB change feed provides a persistent, ordered log of inserts and updates for a container so consumers do not need to poll with full container listings. Event Grid and Event Hubs belong to messaging skills outside this Cosmos change-feed item. A timer that lists items is inefficient polling and is not the official notification mechanism.
