> Right now, when the future fails with an exception, we send that exception to the client, and retry with a new server. but when using ratis server when resource unavailable exception future fails with exceptionally. So, in this case we need to wrap the exception and retry to the same server with some retry policy like MultiLinearRandomRetry or some retry policy.
