public abstract class Operation
extends org.apache.kudu.client.KuduRpc<OperationResponse>

Base class for the RPCs that related to WriteRequestPB. It contains almost all the logic and knows how to serialize its child classes. TODO(todd): this should not extend KuduRpc. Rather, we should make single-operation writes just use a Batch instance with a single operation in it.
