Can you describe your data architecture, specifically how you transition data from the silver layer to the gold layer?

Your architecture likely follows the bronze‑silver‑gold pattern. In the silver layer you store semi‑structured, cleaned data that is ready for transformation. To move data to gold, you apply business rules, aggregation, and schema enforcement. The transition involves: 1) validating data quality; 2) applying transformations (e.g., type casting, derived columns); 3) partitioning and indexing for performance; and 4) writing the result to a gold table that is optimized for analytics. You may also maintain lineage metadata so that you can trace back from gold to silver. The gold layer is typically read‑optimized, often stored in columnar formats like Parquet or ORC, and may be exposed via a BI layer or a data warehouse. The key is to keep the silver layer as a staging area that can be re‑processed if source schemas change, while the gold layer remains stable for end‑users.
