-
-Whilst this is not, specifically, a high-availability plugin configuration, it plays
-an important role on which events are forwarded to peers.
-
-If `instanceId` is set, events produced by that Gerrit instance will contain its
-origin in the `instanceId` field, allowing to track where they are coming from.
-
-The high-availability plugin will check the `instanceId` value to decide whether
-an event should be forwarded: events that originated from different Gerrit instances
-will not be forwarded.
-
-When neither `gerrit.instanceId` nor `event.instanceId` are set, it is not possible
-to identify the origin of the event and thus the event is always forwarded.
