------------------------------------
Summary: Projectable ProjectableTableSource interface doesn't
compatible with BoundedOutOfOrdernessTimestampExtractor
Key: FLINK-7179
URL: https://issues.apache.org/jira/browse/FLINK-7179
Project: Flink
Issue Type: Bug
Components: Table API & SQL
Affects Versions: 1.3.1
Reporter: Zhenqiu Huang
In the implementation of window of stream sql,
BoundedOutOfOrdernessTimestampExtractor is designed to extract row time from
each row. It assumes the ts field is in the data stream by default. On the
other hand, ProjectableTableSource is designed to help projection push down. If
there is no row time related field in a query, the extractor can't function
well.
