Timo Walther commented on FLINK-19912:
--------------------------------------
I think we should make this format-dependent and look at the standards. Looking
at https://www.json.org/json-en.html the page is clear that the key must always
be a string. So we should call `CAST(field AS STRING)` for every key which
means {{null == "null"}}, instead of dropping the value. But I understand that
not everyone likes this. How about we introduce a config option for this. Every
developer should be able to decide about the behavior manually. The default
could be failing such that users are forced to think about this topic.
