Marquez

Submodule: components/marquez → git@github.com:zndx/oss-marquez.git (main).

Marquez-web is the OpenLineage UI. It proxies /api/v1 and /api/v2beta to Atlas. Lineage events, jobs, datasets, and graphs live in AGE on the Signals Postgres. Architecture: OpenLineage + Atlas.

Port convention

Marquez UI port = Atlas HTTP port + 1.

ServiceDefault portEnv override
Atlas21010SIGNALS_ATLAS_HTTP_PORT (process uses fixed -port 21010 today; keep in sync)
Marquez-web21011MARQUEZ_WEB_PORT (default ATLAS + 1)
OL proxy targetAtlas host/portSIGNALS_OL_API_HOST / SIGNALS_OL_API_PORT

:3000 is reserved for ad-hoc local frontend dev (Vite/CRA, Atelier, etc.) and must not be the lab Marquez bind.

LAN example (this project’s Atlas on the node IP):

  • Atlas: http://192.168.1.55:21010
  • Marquez UI: http://192.168.1.55:21011 → proxies /api/v1 + /api/v2beta → Atlas

Ops

devenv tasks run marquez:build-web   # also before devenv up
# UI → Atlas OL
# http://localhost:21011  (or http://<node>:21011)
# proxies to SIGNALS_OL_API_HOST:PORT (default 127.0.0.1:21010)

Acceptance (API completeness)

Marquez-web boot and navigation must not hit 404s on the Marquez API surface. Minimum probe against Atlas (not Marquez API):

for p in health tags jobs namespaces events/lineage stats/lineage-events search?q=test; do
  code=$(curl -sS -o /dev/null -w '%{http_code}' "http://127.0.0.1:21010/api/v1/$p")
  echo "$code  /api/v1/$p"
done
curl -sS -o /dev/null -w '%{http_code}\n' 'http://127.0.0.1:21010/api/v2beta/search/jobs?q=test'

Expect 200 (empty collections are fine). After seeding RunEvents via POST /api/v1/lineage, the UI jobs/datasets/events/lineage views should show content.
