Is it mandatory to return SseEmitter object in rest response?

[@dmitrykovalchuk9705]

Thank you for this tip, Josh! I have a question regarding second part of the video. Do we really need to specify which mime type must be produced by request handler? It seems to me that spring should treat request handler that has Flux as a return type as text/event-stream by default. Is that a correct assumption?

[@coffeesoftware]

Thanks for watching! It should be specified because if you return a Flux without a mimetype Spring WebFlux treats it like returning a Collection - it'll just visit and emit every record as a REST response (which is a different protocol than SSE).

[@dmitrykovalchuk9705]

Thanks for pretty exhaustive explanation
