Summary of Changes

Hello @HunterLine, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the data loading capabilities by extending support for compressed JSON and JSONL formats, specifically .gz and .zst files. It integrates these new formats into the Ray dataset reading pipeline and ensures that the system's file utilities and formatters can correctly recognize and handle them. This change improves flexibility when working with various compressed data sources.

Highlights

• Expanded File Format Support: Added support for reading json.gz and jsonl.gz compressed JSON files across the system.
• Ray Dataset Integration: Enabled Ray datasets to natively support reading json.gz, jsonl.gz, json.zst, and jsonl.zst formats.
• Suffix Recognition: Updated file utility functions and JSON formatter to correctly identify and process files with .gz and .zst suffixes for JSON and JSONL formats.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog

• data_juicer/core/data/load_strategy.py
  • Extended the list of recognized data formats to include 'json.gz', 'jsonl.gz', 'json.zst', and 'jsonl.zst' when determining whether to use read_json_stream.

  • Expanded the default file_extensions list in read_json_stream to include 'json.gz', 'jsonl.gz', 'json.zst', and 'jsonl.zst' for proper file identification.
• data_juicer/format/json_formatter.py
  • Modified the SUFFIXES class variable to include 'json.gz', 'jsonl.gz', 'json.zst', and 'jsonl.zst' as valid JSON-related file suffixes.
• data_juicer/utils/file_utils.py
  • Imported GzipExtractor to handle gzip-compressed files.

Code Review

This pull request adds support for reading gzipped and zstd compressed JSON and JSONL files, including for Ray Datasets. The changes look good and extend the data loading capabilities. I've added a few comments with suggestions to improve code consistency and maintainability, such as standardizing string quotes and suffix formats, and a suggestion to refactor some duplicated code.
