tooptoop4 opened a new pull request #2572:
URL: https://github.com/apache/hudi/pull/2572


   Makes it clearer, ie for example when dealing with data like:
   
   if record key is columnA then the table will get 2 rows if write mode is UPSERT for below incoming data:
   row 1: columnA=abc,columnB=def
   row 2: columnA=abc,columnB=xyx
   row 3: columnA=jkl,columnB=rew
   
   if record key is columnA then the table will get 3 rows if write mode is INSERT for below incoming data:
   row 1: columnA=abc,columnB=def
   row 2: columnA=abc,columnB=xyx
   row 3: columnA=jkl,columnB=rew
