public class HelixReadOnlyZKSharedSchemaRepository
extends HelixReadOnlySchemaRepository

This repository is used to retrieve all the zk shared system store schemas from the system store cluster. The reason to introduce this class is that this class needs to use a HelixReadOnlyZKSharedSystemStoreRepository to make sure that this repo only accesses the schemas belonging to zk shared system stores to avoid unnnecessary zk watches.
