Data Lineage Exploration
The lineage graph is a projection of the ledger — pinned to a specific ULID range. LineageGraphRendered entries record what a viewer saw and when, so historical lineage views are reproducible bit‑for‑bit.
Magellan's lineage explorer presents an interactive, navigable map of data flows across your entire ecosystem.
Starting from any data element, users can trace upstream to discover where data originates and downstream to see where it flows.
The visualization supports filtering by system, schema, data domain, and time range, making it practical to explore even the most complex data landscapes.
Each rendered view writes a `LineageGraphRendered` entry recording the actor, the ULID range the graph was computed against, and the filter parameters. Re-rendering at the pinned ULID range is guaranteed to produce the same graph.
Lineage information powers compliance reporting, root‑cause analysis for data quality issues, and change impact assessment.
Audit ledger entries written by this feature
Each action in this feature appends one of the following entry types to the ULID‑keyed, SHA‑256 hash‑chained audit ledger. A reviewer can replay the chain to reconstruct exactly what happened, when, and under which role.
