Yijie Shen created FLINK-3754:
---------------------------------
Summary: Add a validation phase before construct RelNode using
TableAPI
Key: FLINK-3754
URL: https://issues.apache.org/jira/browse/FLINK-3754
Project: Flink
Issue Type: Improvement
Components: Table API
Affects Versions: 1.0.0
Reporter: Yijie Shen
Assignee: Yijie Shen
Unlike sql string's execution, which have a separate validation phase before
RelNode construction, Table API lacks the counterparts and the validation is
scattered in many places.
I suggest to add a single validation phase and detect problems as early as
possible.
