Current-State Inventory
Purpose
Answers: What does this organization actually have, and how much of that do we know rather than assume?
The second half is the point. An inventory that lists components without grading them reads as knowledge and is often mostly hearsay — a slide box and a running production system look identical in a table. The evidence grade is what separates them, and it is the artifact’s reason to exist.

# Current-State Inventory: Analytics Estate
Register of what Northwind Retail already runs for reporting and analytics,
each entry graded for evidence. **This is a survey, not a target.** The
warehouse consolidation decision lives in [[architecture]] and ADR-014.
## Scope and Boundary
- Estate: reporting, analytics and the pipelines feeding them
- Surveyed: 3–17 March 2026
- Excluded: transactional systems (covered by the order-platform inventory);
marketing SaaS, which Marketing Ops owns and has not shared
- Owner: Priya Raman, Data Platform
## Evidence Grades
| Grade | Means |
|-------|-------|
| **Evidenced** | A named source attests it exists and works this way. Cited, with a date. |
| **Partial** | It exists, but a design-defining fact about it is unrecorded. |
| **Assumed** | Claimed, with no source. It may be real; we cannot say so. |
| **Aspirational** | Target state. It does not exist today. |
| **Spike-open** | A design-defining fact is assumed *and* blocks a decision. |
An entry graded Evidenced with no citation is Assumed.
## Inventory
### Ingestion
| Component | Supplier / incumbent | Grade | Evidence |
|-----------|----------------------|-------|----------|
| Nightly ETL | Airflow 2.6, self-hosted | Evidenced | Runbook walkthrough, Priya Raman, 5 Mar 2026. 41 DAGs, 02:00 UTC |
| CDC from orders DB | Debezium | Partial | Confirmed running (Priya, 5 Mar). Which tables it covers is unrecorded |
| Partner SFTP drops | — | Assumed | Named on the 2024 platform diagram; no owner found, no job scheduling it |
### Storage
| Component | Supplier / incumbent | Grade | Evidence |
|-----------|----------------------|-------|----------|
| Warehouse | Redshift, 4-node ra3.xlplus | Evidenced | Billing console, 6 Mar 2026 |
| Lake | S3, `nw-analytics-raw` | Partial | Exists (console). Retention policy and access model unrecorded |
| Lakehouse | Iceberg on S3 | Aspirational | On the FY27 plan. No table, no catalog, no owner |
### Consumption
| Component | Supplier / incumbent | Grade | Evidence |
|-----------|----------------------|-------|----------|
| Exec dashboards | Looker | Evidenced | Licence renewal, 12 Mar 2026. 9 of 340 dashboards viewed weekly |
| Ad-hoc SQL | Redshift Query Editor | Evidenced | Query logs, 11 Mar 2026 |
| Notebooks | — | Spike-open | Analysts describe "notebooks" without naming a platform. Blocks the compute-isolation decision in ADR-014 |
| Embedded reporting | — | Assumed | On the diagram. No consumer found |
## Totals
Tallied from the rows above, 17 March 2026.
| Grade | Count | Share |
|-------|-------|-------|
| Evidenced | 4 | 40% |
| Partial | 2 | 20% |
| Aspirational | 1 | 10% |
| Assumed | 2 | 20% |
| Spike-open | 1 | 10% |
**3 of 10 entries have no evidence they exist** — the Assumed and Aspirational
rows. Two of those three are on the 2024 platform diagram and nowhere else,
which is the strongest argument in this document for retiring that diagram.
## Open Questions
| # | Question | Blocks | Owner |
|---|----------|--------|-------|
| 1 | Which tables does CDC actually cover? | Warehouse consolidation scope | Priya Raman |
| 2 | What do analysts mean by "notebooks"? | ADR-014 compute isolation | Sam Okafor |
| 3 | Does anything consume the partner SFTP drops? | Whether ingestion can be retired | Priya Raman |
