I was thinking that the pre-fetch logic could be pushed into the ParquetRecordBatchStream itself. I made a proof-of-concept of this here: https://github.com/masonh22/arrow-rs/commit/4f682b1277261dafbb40297529dc3381b0d1c32b I didn't add any performance tests, but I confirmed that this sped things up in my own project by effectively removing the cost of decoding since reading the data takes longer than decoding it. -- This is an automated message from the Apache Git Service.
