-----------------------------------
Summary: Port OperationTreeBuilder to Java
Key: FLINK-12906
URL: https://issues.apache.org/jira/browse/FLINK-12906
Project: Flink
Issue Type: Improvement
Components: Table SQL / API
Reporter: Hequn Cheng
Assignee: Hequn Cheng
As discussed with [~dawidwys], even we can't move it to the API module yet, but
we could already migrate it to java. This might be a good idea, because some
new features added there that use scala features, any such additions are making
the future migration harder.
