T - the class that the ServerCallable handles@InterfaceAudience.Private public abstract class NoncedRegionServerCallable<T> extends ClientServiceCallable<T>
RegionServerCallable.call(int) to
trigger the rpc. The RegionServerCallable.call(int) eventually invokes your
#rpcCall(RpcController) meanwhile saving you having to write a bunch of
boilerplate. The RegionServerCallable.call(int) implementation is from RpcRetryingCaller so rpcs are
retried on fail.
TODO: this class is actually tied to one region, because most of the paths make use of the regioninfo part of location when building requests. The only reason it works for multi-region requests (e.g. batch) is that they happen to not use the region parts. This could be done cleaner (e.g. having a generic parameter and 2 derived classes, RegionCallable and actual RegionServerCallable with ServerName.
