   > So the contract says that things should CASCADE by default. Which is why 
it's not exposed to Iceberg or other connectors.
   
   Yea, that's my point.

   I realized it when I looked through the codebase. 
   
   > Please let me know when you have a completed version of the TPC-DS suite 
in Kyuubi that works with Iceberg.
   
   The suite I show you only do a verification of TPC-DS query result schema. 
   
   The most important role of Kyuubi is a gateway of Spark SQL, just like Spark 
Thrift Server, exposing Spark SQL as a HiveServer2 compatible Service. 
   
   Basically, the suite creates all empty tables, then run all TPCDS query on 
the empty tables and verify the output schemas match the golden file, this 
process works well with iceberg. The error only occurs in the last step, clean 
up tables, when I switch the table format from delta to iceberg.
