@cloud-fan @HyukjinKwon Thanks for comment. So let me get more ideas from you. This is like a syntax sugar to more easily express complex nested `withField` chain. I think we can explicitly expression it by using `transform` + `withField`, but as it goes deeply more, the syntax becomes hard to express and read. This doesn't create new syntax other than `a.b` used to access nested field in array, but just leverages existing one. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
