Hi, All! I have a question concerning the following info from Flink:

15:05:22.357 [main] INFO  o.a.f.a.java.typeutils.TypeExtractor -- Field Person#hobbies will be processed as GenericType. Please read the Flink documentation on "Data Types & Serialization" for details of the effect on performance and schema evolution.

I have the following class:

public class Person {

    private String name;
    private List<String> hobbies;

    public Person() {
    }

    public Person(String name, List<String> hobbies) {
        this.name = name;
        this.hobbies = hobbies;
    }
// getters and setters
}

and I prepared this `TypeInformation`:

TypeInformation<Person> personTypeInformation = Types.POJO(Person.class, Map.of(
    "name", Types.STRING,
    "hobbies", Types.LIST(Types.STRING)));

I saw a few options that don't work for me: •

@TypeInfo(PersonSerializerFactory.class)

- but I can't use this approach because the

Person

class is in a different module. •

returns

method, e.g.:

env.fromCollection(persons)
   .returns(personTypeInformation)

but this doesn't seem to remove the problem. How can I add this type information to the environment?
