li-boxuan opened a new pull request, #9506: URL: https://github.com/apache/incubator-gluten/pull/9506
## What changes were proposed in this pull request? In RasOffload.scala, we discard a plan if the offload doesn't succeed. We do this check by `offloaded.fastEquals(rewritten)`. This is not the most efficient way, and has false positive discards. For example, in TPC-DS, we have observed that q44 & q49 didn't offload `WindowExec` to `WindowExecTransformer` with legacy RAS, and the reason is `WindowExecTransformer` is deemed as "equal" to its `WindowExec` counterparty. ## How was this patch tested? (Please explain how this patch was tested. E.g. unit tests, integration tests, manual tests) (If this patch involves UI changes, please attach a screenshot; otherwise, remove this) -- This is an automated message from the Apache Git Service.
