>            Priority: Major
>              Labels: ignite-3

> h3. Motivation
> The MetaStorageManager#registerWatch method was removed in  IGNITE-18413. Usage of 'registerWatch' was changed on 'registerWatchByPrefix' in DistributionZoneManager. So now WatchListener in DistributionZoneManager is triggered not only by key 'distributionZones.logicalTopology' but also 'distributionZones.logicalTopologyVersion'.
> h3. Definition of Done
> Need to check where 'registerWatch' was used and return the ability to listen to one specific key.
