This ensures that principals can view only the\nroles, privileges, and models that they have access to.\n\nRow filtering also applies to the following model-related views: \n\n### GoogleSQL\n\n- [`INFORMATION_SCHEMA.MODELS`](/spanner/docs/information-schema#models)\n- [`INFORMATION_SCHEMA.MODEL_OPTIONS`](/spanner/docs/information-schema#model-options)\n- [`INFORMATION_SCHEMA.MODEL_COLUMNS`](/spanner/docs/information-schema#model-columns)\n- [`INFORMATION_SCHEMA.MODEL_COLUMN_OPTIONS`](/spanner/docs/information-schema#model-column-options)\n\nThe system role `spanner_info_reader` and its members always see an unfiltered\n`INFORMATION_SCHEMA`.\n\nMore information\n----------------\n\n- [About models](/spanner/docs/ml)\n- [Create and manage models](/spanner/docs/ml-tutorial)\n- [About fine-grained access control](/spanner/docs/fgac-about)"]]
