Jingsong Lee updated FLINK-13393:
---------------------------------
Priority: Major (was: Blocker)
> Blink-planner not support generic TableSource
> ---------------------------------------------
>
> Key: FLINK-13393
> URL: https://issues.apache.org/jira/browse/FLINK-13393
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Planner
> Reporter: Jingsong Lee
> Assignee: Jingsong Lee
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.9.0, 1.10.0
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Now there is a exception when user use table source like:
> {code:java}
> class MyTableSource[T] extend StreamTableSource[T]
> {code}
> The reason is that blink-planner use TypeExtractor to extract class from
> TableSource, and use this class to DataFormatConverter.
> Now, table source has DataType return type, so we don't need extract class
> from TableSource, we can just use conversionClass of DataType.
