----------------------------------
Summary: Introduce TableOperatorWrapperGenerator to translate
transformation DAG in a multiple-input node to TableOperatorWrapper DAG
Key: FLINK-19737
URL: https://issues.apache.org/jira/browse/FLINK-19737
Project: Flink
Issue Type: Sub-task
Components: Table SQL / Planner
Reporter: godfrey he
Assignee: godfrey he
Fix For: 1.12.0
{{Transformation}} is not serializable, while {{StreamOperatorFactory}} is. We
need to introduce another class (named {{TableOperatorWrapper}}) to store the
information of a {{Transformation}}, and introduce a utility class (named
{{TableOperatorWrapper}}) to convert the {{Transformation}} DAG to
{{TableOperatorWrapper}} DAG.
