This interface is for named tables, not path-based tables. I think that
would probably be a different interface because not all sources can support
path-based tables. Cassandra and JDBC are good examples.
For the table metadata, I think we do need partitions. Iceberg creates
partitioned tables and I'd like to start getting the DDL operations working.
This is why I proposed this metadata on the SPIP a few months ago. We seem to
have lazy consensus around it.
