public abstract class OperationRequest
extends SessionRequest

Client operation request.

Operation requests are sent by clients to servers to execute operations on the replicated state machine. Each operation request must be sequenced with a sequenceNumber() number. All operations will be applied to replicated state machines in the sequence in which they were sent by the client. Sequence numbers must always be sequential, and in the event that an operation request fails, it must be resent by the client.
