Data Lineage
Data Management
Metadata describing origin, transformations, and movement of data across pipelines and systems.
Definition
Data lineage documents the source of data, transformation steps (ETL/ELT), and destination systems. It supports auditability, debugging, and compliance (including deletion propagation).
Why this matters
Why it matters: Without lineage, organizations may fail to apply retention or deletion consistently across derived datasets.
Example
Example: Maintain lineage graphs for pipelines so deletion requests propagate to downstream tables and reports.
