Does the DatatypeHint with bridgedTo can meet your requirements?
For example:
'
public @DataTypeHint(
value = "RAW",
bridgedTo = JSONObject .class,
rawSerializer = JSONObject Serializer.class) JSONObject eval(String str) {
return JSONObject .parse(str);
}
'
You may need to provide a class like JSONObject Serializer that extends
TypeSerializerSingleton.

主题: How to return JSON Object from UDF
Hi Team,
I am using Flink 1.13.6 and I have created a UDF and I want to return
JSONObject from that UDF or basically an Object but it doesn't seems to work as
there is no datatype hint compatible to Object. in earlier flink versions when
DataTypeHint wasn't there, it used to work. Any help would be appreciated.
Thanks and Regards ,
Surendra Lalwani
