A developer details a data engineering tactic for consolidating wide CSVs with inconsistent column names and units. The method uses JSON configuration files to map source columns to a standard schema, transforming data into an Entity-Attribute-Value (EAV) long format before pivoting it into a final 'gold' data mart for analysis.

A classic data engineering pattern: config over hard-coded pipeline logic. This approach reduces maintenance overhead for products that must ingest heterogeneous data sources from multiple customers or vendors.
