Class ReplicationStartSyncMessage

java.lang.Object

org.apache.activemq.artemis.core.protocol.core.impl.PacketImpl

org.apache.activemq.artemis.core.protocol.core.impl.wireformat.ReplicationStartSyncMessage

All Implemented Interfaces:

Packet

public class ReplicationStartSyncMessage
extends PacketImpl

This message may signal start or end of the replication synchronization.

At start, it sends all fileIDs used in a given journal live server to the backup, so the backup can reserve those IDs.
