After our offline discussion and investigation, we confirmed that Parquet cannot achieve true zero-copy from disk to memory because its data is stored in compressed and encoded form and must be decoded before use. We’ll continue using Parquet for now given its convenience and practicality, and I’ve updated the TODO to migrate the encoder to a chunk-based API. I would follow up on Arrow IPC as a potential path toward a real zero-copy data pipeline. -- This is an automated message from the Apache Git Service.
