🕒 21:20–21:45
🏷️ Labels: ETL, Unicode, Python, Data Processing, Modularization
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The primary aim was to enhance the ETL pipeline by modularizing it and resolving Unicode handling issues in JSONL files.

Key Activities

  • Modularizing ETL Pipeline: Steps were outlined to define functions and add output actions for enriched data, facilitating easier debugging and downstream usage.
  • Handling Unicode Escapes: Solutions were provided for decoding Unicode escape sequences in JSONL files using pandas, ensuring proper character representation.
  • Unicode Fix for ETL Scripts: A Python code snippet was implemented to fix escaped Unicode sequences in specific dataframe columns without rewriting the entire ETL process.
  • Structured Digest Generation: Methods were outlined to generate compact summaries for datasets of articles related to seed ideas, including a step-by-step plan and a minimal Python function.

Achievements

  • Successfully modularized the ETL pipeline, enhancing maintainability and debugging.
  • Resolved Unicode handling issues in JSONL files, ensuring accurate data processing.
  • Developed a structured approach for digest generation, improving data summarization.

Pending Tasks

  • Further testing of the modularized ETL pipeline with larger datasets to ensure robustness.
  • Integration of the digest generation function into the existing data processing workflow.
