Research direction
The issue names the Vectorized Reader and links migration documentation for the original PARQUET-302 report. Read that migration documentation and the Vectorized Reader entry points first; the stated goal is to avoid decoding data until it is required, but the payload does not identify files, tests, or a precise completion scope.
