Conceptual Workflow Code Implementation 1. Sample Metadata Table Here’s how the metadata table might look (e.g., stored in a Hive table or a CSV): step_id step_type code_or_query output_view 1 SQL SELECT category, SUM(sales_amount) AS total_sales FROM sales_data GROUP BY category category_totals 2 SQL SELECT * FROM category_totals WHERE total_sales > 400 filtered_totals 3 DataFrame filtered_df…

ETL Workflow with Enhanced Logging and Snapshot Management Below is a refined ETL architecture and corresponding SQL and Python updates, based on your project structure and requirements. SQL Table Definitions Control Table The control table is used to manage ETL steps, track their sequence, and specify configurations such as write_mode and snapshot_mode. Log Table The…
