mojo-parquet

mojo-parquet is a from-scratch Apache Parquet library for Mojo 1.1.

The runtime reads and writes a Parquet file: the footer, row groups, column chunks, and data pages. A code generator turns a JSON Schema document into a Mojo struct. None of this code wraps a C, C++, or Rust Parquet library.
