> It would be useful to have an alternative Parquet record reader that is based on the ParquetRecordReader in the parquet-hadoop package. We can then do some tests to see if there are cases where one is preferable over the other.
> The advantages of this new implementation include:
> pushing filter into the scan
> easier code maintenance
