Assignee: Zhenqiu Huang
> 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
> Assignee: 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.
