   > * Based on that the root cause for the performance regression of 
`SubExprEliminationBenchmark` is not due to the codegen implementation of 
`from_json`(the root cause is that the operator `FilterExEc` did not implement 
`SubExprElimination` optimization in `WSC`), this PR will close here.
   > * The operator `FilterExec` implementing `SubExprElimination` optimization 
in `WSC` is still being explored for implementation: [[Only Test][Don't Review] 
Make `FilterExec` to support `subexpressionElimination` in the codegen scenario 
#49573](https://github.com/apache/spark/pull/49573)
   
   Got, although the performance result may degrade, I suggest submitting a pr 
to update the benchmark results of `SubExprEliminationBenchmark ` for Apache 
Spark 4.0 and leave a TODO.
