                 Key: FLINK-6764
                 URL: https://issues.apache.org/jira/browse/FLINK-6764

          Components: Type Serialization System
    Affects Versions: 1.3.0, 1.4.0
            Reporter: Till Rohrmann


Composite type serializer, such as the {{PojoSerializer}}, could be improved by deduplicating stateless {{TypeSerializer}} when being serialized. This would decrease their serialization size.
