   I don't think so. Besides, in our production, we use different namespace schema for different table type. For example, tables under namespace iceberg_{biz_id} are all iceberg tables, tables under namespace hive_{biz_id} are all hive partition tables. It's  wasting time for method call `List<Table> tableObjects = clients.run(client -> client.getTableObjectsByName(database, tableNames))` in our env.
