com.linkedin.venice.controller.helix.SharedHelixReadOnlyZKSharedSchemaRepository

All Implemented Interfaces:

ReadOnlySchemaRepository, StoreDataChangedListener, VeniceResource, Closeable, AutoCloseable

public class SharedHelixReadOnlyZKSharedSchemaRepository
extends HelixReadOnlyZKSharedSchemaRepository
implements Closeable

This class is intended to only be used in Controller, which is sharing one instance across all the clusters. Since the leader->standby transition for a given cluster will clear all the resources, this implementation will do nothing in clear() since it will be shared across all the clusters, whose leader are in the same Controller node.
