> * 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) @panbingkun is currently on vacation. According to @panbingkun's intention, if `FilterExec` supports subexpressionElimination in the codegen scenario, this pr would not be needed. BUt, https://github.com/apache/spark/pull/49573 is still under development. -- This is an automated message from the Apache Git Service.
