Interface StoreGraveyard

All Known Implementing Classes:
HelixStoreGraveyard
public interface StoreGraveyard
The graveyard used to keep all deleted stores. While re-creating a store, Venice could retrieve the important info like largest used version number to avoid resource conflict caused by the same name.

Like the store repository, each cluster should have its own store graveyard instance.
