   > Hi @twalthr
   > Current implementation will reach the limits if a field becomes too large. This can
be reproduced by creating a filed produced by concat_ws(). see [hequn8128@871fb2c](https://github.com/hequn8128/flink/commit/871fb2c7723c11dd0b75176a3be3be70e2740b2b)
   > Best, Hequn
   
   @hequn8128 I use your test case in this PR [FLINK-8921](https://github.com/apache/flink/pull/6921),
thanks
