> Reduce the overhead of conversion between DataStream and Table
> --------------------------------------------------------------
>
> Key: FLINK-31240
> URL: https://issues.apache.org/jira/browse/FLINK-31240
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Reporter: Jiang Xin
> Priority: Major
> Labels: pull-request-available
>
> In some cases, users may need to convert the underlying DataStream to Table
> and then convert it back to DataStream(e.g. some Flink ML libraries accept a
> Table as input and convert it to DataStream for calculation.). This would
> cause unnecessary overhead because of data conversion between the internal
> data type and the external data type.
> We can reduce the overhead by checking if there are paired
> `fromDataStream`/`toDataStream` function call without any transformation, if
> so using the source datastream directly.
