The MiddleManager and Indexer use this resource to serve intermediary shuffle + * data. + * + * We use {@link StateResourceFilter} here because it performs an admin-like authorization and + * all endpoints here are supposed to be used for only internal communcation. + * Another possible alternate could be performing datasource-level authorization as in TaskResourceFilter. + * However, datasource information is not available in middleManagers or indexers yet which makes hard to use it. + * We could develop a new ResourceFileter in the future if needed.
