rusackas opened a new pull request, #40912:
URL: https://github.com/apache/superset/pull/40912
### SUMMARY
Adopts #37701 by @qf-jonathan — thank you for the substantial work here! 🙏
Adds interactive **Sankey-based lineage** that lets users explore data
relationships:
- **Dataset lineage** — upstream database and downstream charts/dashboards
- **Chart lineage** — database → dataset → chart → dashboards pipeline
- **Dashboard lineage** — all upstream databases, datasets and charts
feeding a dashboard
**Implementation:** three REST endpoints
(`/api/v1/lineage/{dataset|chart|dashboard}/<id>`) with permissions +
integration tests, and a `LineageView`/`LineageModal` frontend (ECharts Sankey)
surfaced from the dataset editor and the chart/dashboard action menus.
### What changed vs. the original PR
Rebased onto current master and updated for drift accumulated since the
original branch (Feb):
- Resolved merge conflicts in `constants.py`, `ChartCard`,
`useHeaderActionsDropdownMenu`, and the chart integration tests.
- Repointed the lineage imports from the now-removed
`@apache-superset/core/ui` to `@apache-superset/core/translation` and `/theme`
(the package layout changed).
- Re-applied the dataset lineage tab onto the **migrated (TypeScript)**
`DatasourceEditor` (it was `.jsx` when the original PR was written).
### TESTING INSTRUCTIONS
Open a dataset → **Lineage** tab; open a chart/dashboard menu → **Lineage**;
verify the Sankey renders upstream/downstream relationships.
Backend: `pytest
tests/integration_tests/{charts,dashboards,datasets}/api_tests.py -k lineage`
### Verification status (honest notes for reviewers)
- ✅ Backend static checks pass locally (mypy, ruff, pylint, license headers).
- ✅ Frontend: prettier clean; the adopted TS files type-check cleanly after
the import fixes.
- ⚠️ `oxlint` and the backend **integration tests** weren't run in my
environment (no DB); CI will exercise both.
- ⚠️ End-to-end feature behavior is best confirmed with a manual smoke test
in a running instance.
