No description
Two complementary signals : pool-side (do we have enough connections
for the load?) and per-request side (does any single handler quietly
run hundreds of queries?). Both feed Prometheus + Grafana + alert
rules.
Pool stats exporter (internal/database/pool_stats_exporter.go) :
- Background goroutine ticks every 15s and feeds the existing
veza_db_connections{state} gauges. Before this, the gauges only
refreshed when /health/deep was hit, so PoolExhaustionImminent
evaluated against stale data.
- Wired into cmd/api/main.go alongside the ledger sampler with a
shutdown hook for clean cancellation.
N+1 detector (internal/database/n1_detector.go +
internal/middleware/n1_query_counter.go) :
- Per-request *int64 counter attached to ctx by the gin
middleware ; GORM after-callback (Query/Create/Update/Delete/
Row/Raw) atomic-adds.
- Cost : one pointer load + one atomic add per query.
- Cardinality bounded by c.FullPath() (templated route, not URL).
- Threshold default 50, override via VEZA_N1_THRESHOLD.
- Histogram veza_db_request_query_count + counter
veza_db_n1_suspicions_total.
Alerts in alert_rules.yml veza_db_pool_n1 group :
- PoolExhaustionImminent (in_use ≥ 90% for 5m)
- PoolStatsExporterStuck (gauges frozen for 10m despite traffic)
- N1QuerySpike (> 3% of requests over threshold for 15m)
- SlowQuerySustained (slow query rate > 2/min for 15m on same op+table)
Tests : 8 detector tests + 4 middleware tests, all pass.

Version courante : v1.0.4 (cleanup + consolidation post-audit). Voir CHANGELOG.md et docs/PROJECT_STATE.md.
Project Structure
apps/web— Frontend React 18 + Vite 5 + TypeScript strict (source of truth for the UI)veza-backend-api— Main Go 1.25 API service (Gin, GORM, Postgres, Redis, RabbitMQ, Elasticsearch). Handles REST, WebSocket, and chat (chat server was merged into this service in v0.502).veza-stream-server— Rust streaming server (Axum 0.8, Tokio 1.35, Symphonia) — HLS, HTTP Range, WebSocket, gRPCveza-common— Shared Rust types and loggingpackages/design-system— Shared design tokens
See CLAUDE.md for the full architecture map.
Development Setup
Prerequisites: Node 20 (see .nvmrc), Go, Rust, Docker. Configure .env from .env.example.
# Verify environment
make doctor
./scripts/validate-env.sh development
# Install dependencies
make install-deps
# Option A — Backend in Docker + Web local
make dev
# Option B — All apps local with hot reload (infra from docker-compose.dev.yml)
make dev-full
# Option C — Infra only, then run services manually
docker compose -f docker-compose.dev.yml up -d
make dev-web # or make dev-backend-api, make dev-stream-server
See docs/ENV_VARIABLES.md for required variables. make build builds all services.
Quick Start
Frontend only
cd apps/web
npm install
npm run dev
Docker Production
Canonical production compose file: docker-compose.prod.yml
docker compose -f docker-compose.prod.yml up -d
See make/config.mk for COMPOSE_PROD and deployment docs.
CI/CD
- Badge : CI status above. Set
SLACK_WEBHOOK_URL(Incoming Webhook) in repo secrets to receive Slack notifications on failure.
Disabled workflows
- Storybook (
chromatic.yml.disabled,storybook-audit.yml.disabled,visual-regression.yml.disabled): deferred until MSW is wired up for/api/v1/auth/meand/api/v1/logs/frontend, which currently causes ~1 400 network errors in the Storybook build. The npm scripts (storybook,build-storybook) still work locally for one-off component inspection. To reactivate in CI, fix the MSW handlers and rename the three files back to.yml.
