-------------------------------------
Summary: Eliminate redundant field initialization when
deserializing POJOs
Key: FLINK-37722
URL: https://issues.apache.org/jira/browse/FLINK-37722
Project: Flink
Issue Type: Sub-task
Components: API / Type Serialization System
Reporter: Zhanghao Chen
Currently, PojoSerializer will first create a new POJO instance and initialize
all the fields (in the createInstance() method), then deserialize and set
fields. The field initialization with in the createInstance() method is
redundant, as all fields will be set later during deserialization anyway. We
should eliminate it for better performance.
