Session Goal

The goal of this session was to refactor an existing ETL pipeline to enforce a canonical ledger schema, improve data processing functions, and implement a layered architecture.

Key Activities

  • Reviewed Python scripts related to file handling and script reading to ensure compatibility with the refactored ETL pipeline.
  • Developed a strategy for code migration, focusing on enforcing a canonical ledger schema and improving data processing functions.
  • Outlined a pragmatic plan for ETL pipeline refactoring, including architectural guidelines and specific file modifications.

Achievements

  • Successfully outlined a structured approach for ETL pipeline refactoring.
  • Developed a checklist and template for code migration, ensuring smooth transition and maintainability.

Pending Tasks

  • Implement the refactoring plan in the actual ETL pipeline.
  • Conduct testing to validate the new architecture and processing functions.
