Thanks Xu Forward for bring up this topic, I think the JSON functions are very useful especially for those MySQL users.
I saw that you have done some work within the Apache Calcite, that’s a good start, but this is one concern from me, Flink doesn’t support JSON type internal, so how to represent a JSON object in Flink maybe a key point we need to resolve. In Calcite, we use ANY type to represent as the JSON, but I don’t think it is the right way to go, maybe we can have a discussion here.
