    Description

      Catalogd RPC requests (TDdlExecRequest, TUpdateCatalogRequest and TResetMetadataRequest) should contain the information (whether in LocalCatalog mode) of the clients (coordinators). For LocalCatalog coordinators, catalogd just need to send back invalidations instead of the full catalog objects.
