Wang Qilong commented on FLINK-35905:
-------------------------------------
Thank you for your reply. We would like to add some additional physical
operator functionality, and a better option may be to inject ColumnarRule
similar to Spark. Through this, we can insert some new physical operators when
converting logical operators to physical operators. However, I have not found
that Flink has similar functionality
> Flink physical operator replacement support

> Project: Flink
> Issue Type: Bug
> Components: API / Scala, Table SQL / API
> Affects Versions: 1.15.0
> Environment: Flink1.15 and so on
> Reporter: Wang Qilong
> Priority: Major
>
> I have been studying the FlinkSQL source code recently and have learned about
> the execution process of FlinkSQL, which has led to a question:
> Does Flinksql provide some SPI implementations that support custom physical
> operators, such as customizing a FileSourceScanExec in the execPhysicalPlan
> layer?
