Notification sent when the replica transitions to streaming mode.

This message is sent to all watchers when the replica completes an RDB transfer and begins streaming mode. It signals that the in-memory state is now synchronized with Redis and subsequent Update messages will follow.

Example

When a watcher receives this message:

  receive do
    {ref, %Vdr.WatchEvent.Init{}} ->
      # Replica is now in streaming mode
      # Future updates will arrive as Update messages
      :ready
  end
