A kingfisher-creek checkout service wants other municipal apps to react to an OrderPlaced event. Where should it publish that application event?
Select an answer to reveal the explanation.
Short Explanation
Your own app events belong on a custom (or namespace) topic. Keep the payload small and reactive—don’t shove OrderPlaced down an Event Hubs telemetry pipe by default.
Full Explanation
Application-defined events such as OrderPlaced are published to Event Grid custom topics (or namespace topics as docs name). Event Hubs fits high-volume streams; Blob logs and Microsoft Graph are not the Event Grid custom-event publish path.
