> For e.g, create web_returns table in tpcds in iceberg format and try to copy
> over data from regular table. More like "insert into web_returns_iceberg as
> select * from web_returns".
> This inserts the data correctly, however there are lot of files present in
> each partition. IMO, dynamic sort optimisation isn't working fine and this
> causes records not to be grouped in the final phase.
