Mirza Aliev updated IGNITE-20287:
---------------------------------
Description:
h3. *Motivation*
We need to clean up resources for destroyed distribution zones from the
catalog. It is possible that while a zone is removed, some actions that must be
done on a zone deletion could be interrupted by restart. On recovery, we must
detect such zone's deletion an must clean up the resources. Currently we store
some zone's state in Meta Storage, so this resources must be cleaned up.
h3. *Definition of done*
Resources for deleted zones are removed as well for deleted zone even if this
removal were interrupted by restart.
h3. *Implementation notes*
For zones that are not presented in the catalog, but presented in the MS, just
remove all data nodes related keys. All these changes must be done using meta
storage condition which we us when we call
{{DistributionZoneManager#removeTriggerKeysAndDataNodes}} on a zone drop.
