They are utilized by expression serdes which we created earlier with their own unit tests. Thats why I didn't create thorough unit tests for this field. I added a commit to include a unit test with `sortTerm` as a function since the `sortTerm` shows which field (`FieldReferenceDTO`) or function (`FuncExpressionDTO`) Gravitino uses to sort the table explained in the documentation. -- This is an automated message from the Apache Git Service.
