Hi:
I believe the ability for Alteryx Designer to read from/write to parquet files will enhance its capability to serve the DSML community better. Potentially someone can design this connector as part of the App community but given the importance parquet file formats have gained as a columnar storage format (as opposed to something like Avro - which is a row storage format), Alteryx supplying native connectors to such files would be awesome.
Thank you,
