--------------------------------
Description:
Does Flinksql provide some SPI implementations that support custom physical
operators, such as customizing a new StreamExecutFileSourceScan and supporting
rule injection for converting logical operators to physical operators
I want to implement the function of adding some additional physical operators.
A better option may be to inject ColumnarRule similar to Spark, which can
insert some new physical operators when converting logical operators to
physical operators. However, I have not found that Flink has similar functions

Does Flinksql provide some SPI implementations that support custom physical
operators, such as customizing a FileSourceScanExec in the execPhysicalPlan
layer?
I have been researching the FlinkSQL source code recently, understanding the
execution process of FlinkSQL, and came up with the above question
