twalthr opened a new pull request #15154:
URL: https://github.com/apache/flink/pull/15154


   ## What is the purpose of the change
   
   This renames the arguments of tuple classes to the corresponding name of the 
field. Having a common name for argument and field is a common pattern for 
POJOs and allows the Table API to treat tuples as regular structured types 
where the constructor fields determine the fields order.
   
   This change should not have any impact on API stability and should be 
portable to older Flink versions without issues.
