Hi, I'm a bit hesitant switching to Iceberg as the default atm. I lean more toward setting the default table format at the database level instead.
Hive Iceberg currently lacks automatic table maintenance, comprehensive support for partition-level statistics, and various partition-aware optimizations (see HIVE-28410) Moreover, we haven't conducted any performance testing so far. It would be helpful to first assess where we currently stand before making a final decision. Regards, Denys
