[GitHub] [hudi] jiegzhan commented on issue #2051: [SUPPORT] insert operation didn't insert a new record, instead it updated existing records in my no-primary-key table

   insert is insert, upsert is upsert, if they mixed up, then the behavior got changed, which made underlying data unreliable anymore. 
   
   Are you planning to insert a new row to 1) an existing small file or 2) a new small file? 
   1) is better since S3 won't have a lot small files after issuing many insert queries.
