public abstract class InitializationMsg
extends ReplicationMsg

This is an abstract class of messages of the replication protocol for message that needs to contain information about the server that send them and the destination servers to which they should be sent.

Initialization messages are used when initializing a new replica from an existing replica: total update messages are sent across the topology from the source replica to the target replica, possibly traversing one or two replication servers in the process (e.g. DS1 -> RS1 -> RS2 -> DS2). For this reason we consider them "routable".

Sender of an initialization message can be a DS or a RS (e.g, in case of Error message). Destination of an initialization message is always a DS.
