public class CommandRequest
extends OperationRequest

Client command request.

Command requests are submitted by clients to the Raft cluster to commit commands to the replicated state machine. Each command request must be associated with a registered SessionRequest.session() and have a unique OperationRequest.sequenceNumber() number within that session. Commands will be applied in the cluster in the order defined by the provided sequence number. Thus, sequence numbers should never be skipped. In the event of a failure of a command request, the request should be resent with the same sequence number. Commands are guaranteed to be applied in sequence order.

Command requests should always be submitted to the server to which the client is connected and will be forwarded to the current cluster leader. In the event that no leader is available, the request will fail and should be resubmitted by the client.
