> Project: Beam
> Issue Type: Improvement
> Components: dsl-sql, io-java-parquet
> Reporter: Ismaël Mejía
> Priority: P3
>
> ParquetIO today uses Avro's GenericRecord to materialize reads from Parquet
> records, this implies an extra conversion from GenericRecord to Beam's Row.
> We can 'push' this conversion into the source read process by implementing a
> RecordMaterializer that builds Rows at read time xtending Parquet's
