All Implemented Interfaces:

BinaryProtocol.WireFormatable

Enclosing class:

Protocol

public class Protocol.RestoreResponse
extends BinaryProtocol.SimpleMessage

Response when the replica needs information to instigate a network restore. The message contains two pieces of information. One is a set of nodes that could be used as the basis for a NetworkBackup so that the request node can become current again. The second is a suitable low vlsn for the replica, which will be registered as this replica's local CBVLSN. This will contribute to the global CBVLSN calculation. The feeder when sending this response must, if it is also the master, update the membership table to set the local CBVLSN for the requesting node thus ensuring that it can continue the replication stream at this VLSN (or higher) when it retries the syncup operation.
