Lineage & Audit Trail
Track bronze → silver → gold promotion with a catalog your compliance team can inspect before models go live.
Track bronze → silver → gold promotion with a catalog your compliance team can inspect before models go live.
Business problem
Regulated industries need to explain which raw inputs fed a report or model. Spreadsheets and ad-hoc pipelines make audits slow and answers unreliable.
Heimdall solution
Heimdall Lake records medallion layers in a unified catalog. Teams can trace any gold dataset back through silver curation to bronze ingest batches before deploying ML or sharing exports.
Business impact
Compliance reviews focus on catalog metadata instead of reverse-engineering scripts. Faster sign-off when models move to production.
How it works
Catalog every ingest
Bronze tables retain source type, upload time, and connection metadata.
Document silver logic
Silver views encode filters and transforms as named datasets — not hidden spreadsheet steps.
Audit before deploy
Review gold lineage with stakeholders, then connect approved gold to intelligence products.
