### Backend VL (Velox) ### Bug description Currently, while executing vectorized etls, we unexpectedly found that inputIteratorTransformer is consuming a significant amount of CPU time. The Spark UI is as follows: <img width="409" alt="image" src="https://github.com/user-attachments/assets/f7e8fe31-efa5-48fc-a4a7-3e5c4fd540b1";> <img width="419" alt="image" src="https://github.com/user-attachments/assets/944ec844-2fa1-4edf-9dd6-b814864f1158";> <img width="452" alt="image" src="https://github.com/user-attachments/assets/1120adc6-9900-423a-82cc-8d2771c0e9c1";> The image shows the process from Table Scan to inputIteratorTransformer. inputIteratorTransformer includes the total execution time of all previous operators, but from the CPU time perspective, it doesn’t seem to be the case.
