Marcel Reutegger resolved OAK-2829.
-----------------------------------
Resolution: Fixed
Fix Version/s: (was: 1.2.3)
I'm resolving this issue as fixed. All sub-tasks, but one (OAK-3001), have been
implemented and tests look OK. The remaining sub-task is a further
optimization, which can be tracked separately IMO.
> Comparing node states for external changes is too slow

> 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.
