Hi @StephanEwen, `int[] selected` in `VectorizedRowBatch` is used by Hive vectorization computation engine. (Hive filter node can do zero-copy filter). ORC `RecordReader` does not use this field. About pushed down predicates, I have done some research and testing, and I think that at least Orc will guarantee the equivalence of `RecordReader.getRowNumber` and `RecordReader.seekToRow`, no matter how many predicates there are. So I think it should be safe. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
