Hi HN! I work on an analytical database engine, and I spend a lot of time trying to understand the structure of Apache Parquet files (row groups, column chunks, data pages, encodings, etc.). I feel like existing tools for this job such as parquet-tools or pyarrow are cumbersome to use and for anything beyond the basics you end up writing custom code.
