   Athena question could boil down to what version of presto its running 
internally. Really for aws folks to answer. 
   
   But on open source Presto, I want to clear up few things. 
   - Hudi tables, do use Presto's native parquet readers.
   - The timeline version filtering for COW/MOR RO queries adds no overhead. 
This has been verified at Uber many times.
