> With {{oak-segment-tar}}, the trigger for running {{cleanup}} on the standby 
> instance could be determined by the GC generation number of the head which is 
> bound to increase every time a cleanup is ran.
> {code}
> fileStore.getHead().getRecordId().getSegment().getGcGeneration();
> {code}
> The current trigger mechanism consists of detecting a 25% size increase over 
> a client cycle (typ. 5 sec).
> This would be dropped in favor of the new detection mechanism.
> The auto-compaction mode would remain configurable.
