Hi Dawid, But the temporary table does not belong to Catalog, actually Catalog doesn't know the existence of the temporary table. Let the table factory of catalog to create source/sink sounds a little sudden.
If we want to make temporary tables belong to Catalog, I think we need to involve catalog when creating temporary tables.
