Motivation
To support a flexible and reliable load balancing strategy, external router (sgl-router) and internal controller (dp-controller) should be aware of the real-time load situation.
Current implementation uses a polling mechanism and a watch-based communicator to query load from the scheduler. However, this is flexible and elegant.
- Implement a piggyback load reporting mechanism, in which load information is carried through restreaming token messages.
- Also keep the watching mode, always storing the latest load information in http worker for external query.
