-------------------------------------
Summary: Introduce a deep copy method of SerializerConfig for
merging with Table configs in
org.apache.flink.table.catalog.DataTypeFactoryImpl
Key: FLINK-34239
URL: https://issues.apache.org/jira/browse/FLINK-34239
Project: Flink
Issue Type: Sub-task
Components: API / Core
Affects Versions: 1.19.0
Reporter: Zhanghao Chen
*Problem*
Currently,
org.apache.flink.table.catalog.DataTypeFactoryImpl#createSerializerExecutionConfig
will create a deep-copy of the SerializerConfig and merge Table config into
it. However, the deep copy is done by manully calling the getter and setter
methods of SerializerConfig, and is prone to human errors, e.g. missing copying
a newly added field in SerializerConfig.
*Proposal*
Introduce a deep copy method for SerializerConfig and replace the curr impl in
org.apache.flink.table.catalog.DataTypeFactoryImpl#createSerializerExecutionConfig.
