Description

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.
