- "As Kai-Hsun mentioned in slack, I think we can simply remove this line, since the behavior in Scenario 1 is not reliable. > I think it is pretty rare, and typically it will hit backoffLimit before the new Pod is ready and the whole cluster needs to restart.

- "> limit: In Ray, users can configure a client-side limit via the RAY_MAX_LIMIT_FROM_API_SERVER environment variable. Should we consider supporting a similar mechanism in the history server? Yes, we can address this together with the timeout in a follow-up. This also observed the same issue in `"
