Jark Wu commented on FLINK-19912:
---------------------------------
Thanks for the suggestion [~twalthr].
I think it's a good idea to have a format option. For example
{{json.map-null-key.behavior}}, the option values can be:
- {{fail}} (default): throw exception
- {{drop}}: drop the null key entries
- {{string-literal}}: serialize the {{null}} key as string literal, {{"null"}}
by defualt, but can be configured by {{json.map-null-key.string-literal}}
option.
> JSON format fails to serialize map value with null keys
