### Change Logs 1. For Spark3.5, add row index (record position) column to the parquet file reader and file group reader. For <= Spark3.4, no such column is added. 2. For Spark3.5, enable record key related filters for positional merging; otherwise for <= Spark3.4. 3. For Spark3.5, read row index (record position) column out from the record. For <= Spark3.4, the position is generated from the positional record buffer. ### Impact 1. Achieved the same filter pushdown functionality for both position and key based merging. 2. Made positional based merging is more attractive. ### Risk level (write none, low medium or high below) Low since we only enabled it for Spark3.5. ### Contributor's checklist - [ ] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute) - [ ] Change Logs and Impact were stated clearly - [ ] Adequate tests were added if applicable - [ ] CI passed -- This is an automated message from the Apache Git Service.
