hangc0276 opened a new issue #12241:
URL: https://github.com/apache/pulsar/issues/12241


   **Describe the bug**
   Python 2 and Python 3 generate object schema without sort in different behavior.
   Take the following class for example
   ```Python
   class T2(Record):
     b = Integer()
     a = Integer()
     d = String()
     c = Double()
   ```
   Python2 generated field schema:
   ```
   [{'type': ['null', 'int'], 'name': 'a'}, {'type': ['null', 'double'], 'name': 'c'}, {'type': ['null', 'int'], 'name': 'b'}, {'type': ['null', 'string'], 'name': 'd'}]
   ```
   
   Python3 generated field schema:
   ```
   [{'type': ['null', 'int'], 'name': 'b'}, {'type': ['null', 'int'], 'name': 'a'}, {'type': ['null', 'string'], 'name': 'd'}, {'type': ['null', 'double'], 'name': 'c'}]
   ```
   
   Python3 generated field schema in POJO field define order, but Python2 generated field schema order is not. It is the dict key order for the field name.
