------------------------------------
Summary: Table#to_pandas check table boundedness
Key: FLINK-31605
URL: https://issues.apache.org/jira/browse/FLINK-31605
Project: Flink
Issue Type: Improvement
Components: API / Python
Affects Versions: 1.17.0
Reporter: Yunfeng Zhou
When `Table#to_pandas` is invoked on a table with an unbounded source, this
method would not throw exceptions. Instead, it would be infinitely executing
without exiting. It would be better to check the boundedness of a table before
execution and throw exceptions on unbounded cases.
It might be possible to reference the code in
`StreamGraphGenerator#existsUnboundedSource` to judge whether a Table is
bounded or not.
