medallion

DE//AGENT currently lists 2 resources under medallion: 1 tutorial, 1 pattern. Everything below is derived from the live registry — counts, capabilities, verification state and security posture come from the curated records, never from marketing copy.

Documented learning objectives across these resources:

• Contrast lake, warehouse, and lakehouse by what each does to raw files — via The lakehouse mental model — lake vs warehouse vs table formats vs zones
• Name the table format's jobs — snapshots, manifests, hidden partitioning, schema evolution — via The lakehouse mental model — lake vs warehouse vs table formats vs zones
• Place the medallion zones over a lakehouse and say who owns each zone — via The lakehouse mental model — lake vs warehouse vs table formats vs zones

These resources map to stage: Lakehouse (2). Follow the four-phase roadmap to place this topic inside a progression instead of learning it in isolation.

Every entry, its shape and its trust state — sorted by the registry's composite score. This table is the honest version of a marketing comparison: no sponsored placements, no unverifiable claims.

How scores are computed: source quality score.

Highest composite score first:

1. Medallion Zones (raw / curated / serving) score 37.25 — beginner
2. The lakehouse mental model — lake vs warehouse vs table formats vs zones score 34.15 — beginner

Scores rank provenance, completeness and trust — read how verification works before adopting anything.

Known limits: A single small pipeline with one consumer,When storage cost dominates and copies are wasteful (Medallion Zones (raw / curated / serving))

• The lakehouse mental model — lake vs warehouse vs table formats vs zones — Build the map before touching a table: object storage is files with no structure for trust or ownership, a table format (Iceberg or Delta) adds snapshots, manifests, hidden partiti… details
