> Looks good, but the current implementation forces a memory copy (Vec allocation) even when we want to use Arrow directly. We should refactor io.rs so that read_parquet_to_arrow is the base implementation, ensuring true zero-copy performance for the pipeline. > > origin: Disk -> Arrow -> Vec (copy) -> Arrow (copy) -> GPU > > we need: Disk -> Arrow -> Arrow (Zero-copy Reference) -> GPU (through Pointer) > > I think so, plz correct me if I'm wrong.
