bithw1 opened a new issue, #17506:
URL: https://github.com/apache/hudi/issues/17506

   ### Describe the problem you faced
   
   I have created a hudi table using  following spark sql, but when I look at 
the .hoodie.properties or run `show create table`, there is no payload class 
there, 
   
   How could I know which payload class this table is using when doing record 
combine, i want to know the combine logic when I am using the table.
   
   
   ```
   CREATE TABLE IF NOT EXISTS hudi_cow_15 (
     a INT,
     b INT,
     c INT
   ) 
   
   USING hudi
   
   tblproperties(
   type='cow',
   primaryKey='a',
   preCombineField='c'
   )
   ```
