Icebird: JavaScript Iceberg Client

Code Analysis

26 files read · 7 rounds

A JavaScript library that reads Apache Iceberg tables from S3 using hyparquet, supporting Parquet and Avro storage formats with position and equality deletes.

Strengths

Well-structured separation of concerns between metadata, manifest processing, and data reading. Properly implements complex Iceberg v1/v2 manifest logic including sequence number inheritance. Good reuse of hyparquet library for core parquet/avro parsing.

Weaknesses

Fragile S3 XML parsing using regex instead of proper SDK. Limited error handling with generic fetch errors. Some TODOs indicate incomplete parallelization and async manifest handling. Missing support for REST/Hive/Glue catalogs limits utility.
