parquet file parser for javascript

Code Analysis

6 files read · 2 rounds

A Node.js library that parses Parquet file footers to extract schema metadata, statistics, and row group information without reading the actual data payload.

Strengths

Deep implementation of the Thrift TCompact protocol for parsing binary Parquet footers; robust handling of complex nested schemas (Maps, Lists) and GeoParquet logical types; efficient streaming support via `readParquetFooter`.

Weaknesses

Lack of comprehensive test coverage visible in the codebase; error handling relies on basic try/catch blocks without detailed error context or validation for malformed footers; synchronous API exists but async is preferred, suggesting potential legacy patterns.
