Ivan Andika updated RATIS-2377:
-------------------------------
Description:
Currently linearizable read might block if the read is not ready to be
processed yet. This might not be desirable in some cases. For example, if a
server only contains a fixed handler threads, this might block one of the
thread for too long which can affect other queued writes / reads.
It might be a good idea to have a mechanism so that the request will return /
throws exception if the request cannot return immediately (similar to
RaftServerImpl#staleReadAsync). In this case, the caller can either return the
exception to client for retry or requeue the call.
