Jingsong Lee commented on FLINK-19847:
--------------------------------------
Even if we want to support nested table join, it should be join on Row or Map
instead of Array.
Because Array is a special struct with index... I am not sure it is safety to
support equals on it.
> Can we create a fast support on the Nested table join?
