Research direction
Read HoodieVectorizedParquetRecordReader and the linked pull-request discussion first, focusing on how batchIdx is currently obtained. Replace the reflection-based access while preserving the reader's existing behavior; done means the reader no longer uses reflection for batchIdx and the relevant project checks pass.
