> Comparing node states for local changes has been improved already with
> OAK-2669. But in a clustered setup generating events for external changes
> cannot make use of the introduced cache and is therefore slower. This can
> result in a growing observation queue, eventually reaching the configured
> limit. See also OAK-2683.
