Data Chain of Custody

The ability to audit our data pipeline is critical.
This is currently managed by the Dolt flow itself. Dolt is built for large-scale data collaboration, and our first line of defense against corrupted data is robust version history and branch protection.
Scrapers live side-by-side with ETL files. Data is scraped to a temporary Hadoop worker where it can be translated by the etl.py file to a common data schema. Since GitHub is a version control tool, we'd be able to reconstruct what a scraper or ETL file looked like at any time in the past for auditing purposes.
