   @beliefer Hive metastore is just an implementation of `ExternalCatalog`. We support different versions of Hive metastore. It cannot be said that the default value is supported when using Hive 3.1 metastore, while the default value is not supported when using Hive 1.2 metastore. One possible implementation is similar to bucket, which is stored in table properties:

   Please correct me if I'm wrong.
