[Question]: The best practice of return result from server side

[vincent-pli]

I'm little confuse about how to return result from server to client, I saw many choices:

• server can return a Message, let client get from the message.parts
• server can return a task, client should get from task.artifacts.part? and in non-stream case, the client should check the task.status to decide if it need to polling the task until it complete and then get the result from final task. artifacts.part, right?

In the stream enabled case, thing is even more complex:
what client expect to get: a task or message or something else, I checked the implements of python, it have 2 more types: TaskStatusUpdateEvent and TaskArtifactUpdateEvent, the server can send back whatever it prefer no restrict.

So do we have any guide or best practice to clarified that, thanks
