   Thanks @bvaradar . 
   
   What is the effect of  `cleaning older file versions` ?  Does this operation 
also delete data?
   
   Task the following operations as an example(15 commits and each commit 
inserts one letter)
                       
   commit id:         1  2 3 4 5 6 7 8 9 10 11 12 13 14 15
   data to insert:    A B C D E F G H I J K L M N O P Q
   
   
   When hudi cleans the old commit from 1 to 5, will A to E also be deleted or 
they are kept(A~E can be queried out with select *)
