public interface Operation<T>
extends Serializable

Base type for Raft state operations.

This is a base interface for operations on the Raft cluster state. Operations are submitted to Raft clusters by clients via a Session. All operations are sent over the network and thus must be serializable by the client and by all servers in the cluster. By default, Java serialization is used. However, it is recommended that operations implement CatalystSerializable or register a TypeSerializer for better performance.
