Implements the Phase 2 hook from the previous commit. With this in
place, UserDisplayService.find chains:
hot cache → DB (user_display_cache) → Keycloak Admin API
so any realm user resolves on first display, even if they never made
an authenticated request to ordinis. The resolved entry is persisted
via UserDisplayService.upsert with source=KEYCLOAK_ON_DEMAND, so the
next render of the same sub hits the DB tier (~ms) instead of going
back to Keycloak.
Implementation notes:
- Spring RestClient (modern blocking HTTP, replaces RestTemplate).
- client_credentials grant against
{issuer}/realms/{realm}/protocol/openid-connect/token. Token cached
in-memory minus a 30s safety margin from `expires_in`.
- 401 on user lookup wipes the cached token and surfaces a
RuntimeException, so the next resolve refetches.
- 404 on user lookup → Optional.empty (definitive miss, sub not in
realm). UserDisplayService logs and the caller falls back to short
UUID. Negative cache TTL not implemented — added complexity not
justified for the current realm size (~50 users).
- Bean activated only when ordinis.keycloak.admin.enabled=true AND
the env vars are set. Default disabled — UserDisplayService treats
KeycloakUserResolver as @Autowired(required = false), so a
deployment without Keycloak admin creds keeps the previous behavior
(DB cache only) instead of crashing on startup.
Application config:
- ORDINIS_KEYCLOAK_ADMIN_ENABLED (false by default)
- ORDINIS_KEYCLOAK_ADMIN_URL e.g. https://auth.nstart.space
- ORDINIS_KEYCLOAK_ADMIN_REALM defaults to nstart
- ORDINIS_KEYCLOAK_ADMIN_CLIENT_ID via vault (see docs-internal/keycloak-admin-setup.md)
- ORDINIS_KEYCLOAK_ADMIN_CLIENT_SECRET via vault
Setup runbook (docs-internal/keycloak-admin-setup.md) covers:
- creating the Keycloak service-account client + assigning view-users
- writing the secret into both vault instances (different per env)
- wiring vault.hashicorp.com agent-inject annotations into the chart
- verification steps + common failure modes
Phase 3 (scheduled bulk sync) is documented at the end of the runbook
but deferred — depends on observed cache miss rate after this lands.
Ordinis
MDM сервис для НСИ ЦУОД ОДХ (Оперативное и Долговременное Хранение). Часть линейки Terravault. Ордо/порядок (от лат. ordo) — упорядоченные классификаторы и справочные данные.
ЦУОД — anchor-клиент v1, второй клиент = свой config bundle, без code change.

Стек
- Java 21, Spring Boot 3.4
- PostgreSQL 18 + PostGIS 3.6 + btree_gist (EXCLUSION CONSTRAINT)
- Apache Kafka 4.2 (KRaft, SASL SCRAM-SHA-512)
- Hibernate Envers (tx-time) + valid_from/valid_to (effective-time) — bitemporal
- Liquibase
- Spring Cloud Config + Spring Cloud Vault (Kubernetes auth)
- Micrometer + Prometheus
- LogstashEncoder JSON stdout → Loki через Alloy
- OpenTelemetry → Tempo (OTLP gRPC)
Архитектурные принципы
- Generic dictionary engine + ЦУОД config bundle (Approach B). Engine не знает про "КА"/"наземные станции" — узнаёт через JSON Schema из bundle
- Bitemporal: Envers для tx-time + valid_from/valid_to для effective-time + EXCLUSION CONSTRAINT
- 3 scope-топика Kafka (
public/internal/restricted) — изоляция через ACL, не через filter в consumer - System boundary: 3 deployable делят БД (master+replica). Внешние consumers — только REST/Kafka, никогда прямо в БД
- Tiered performance: 1k RPS из коробки (PG replica + Caffeine). 10k+ RPS включается per-dictionary через Redis projection
- Audit log в БД (compliance), технические логи в Loki
