Ingo Bürk commented on FLINK-24387:
-----------------------------------
JSON_STRING sounds like a good fit to me.
> Support a "to JSON" function

> Key: FLINK-24387
> URL: https://issues.apache.org/jira/browse/FLINK-24387
> Project: Flink
> Issue Type: Sub-task
> Reporter: Ingo Bürk
> Priority: Major
>
> We should consider adding a TO_JSON function which can simply convert some
> (supported) type directly into a JSON representation, e.g. the equivalent of
> doing
> {code:java}
> JSON_QUERY(JSON_ARRAY(x), '$.[0]'){code}
