---------------------------------
Epic Link: IGNITE-20611 (was: IGNITE-20166)
> Clean up abandoned resources for destroyed zones in catalog
> -----------------------------------------------------------
>
> Key: IGNITE-20287
> URL: https://issues.apache.org/jira/browse/IGNITE-20287
> Project: Ignite
> Issue Type: Improvement
> Reporter: Kirill Tkalenko
> Priority: Major
> Labels: ignite-3
>
> 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 a 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.
