Could you build this?
Partial While Ruby code is easy to write, implementing the full Apache Parquet specification (Thrift metadata, bit-packing, run-length encoding, dictionary encoding, and columnar serialization) completely from scratch requires meticulous binary format parsing.
What it would actually take: Requires implementing binary deserializers for the Apache Parquet format in pure Ruby, including Thrift protocol parsers for file metadata and readers for Snappy/GZIP/ZSTD/LZ4 page compression. The challenge lies in accurately parsing bit-packed and run-length-encoded (RLE) definition/repetition levels for nested structures and achieving acceptable I/O performance without native C extensions.
