Palantir Production Checklist

Code Quality

• All tests passing including Foundry integration tests
• No hardcoded hostnames, tokens, or RIDs
• Error handling covers all Foundry ApiError status codes
• Rate limiting with exponential backoff implemented
• Logging uses structured format (JSON) with request IDs

Infrastructure

• Health check endpoint verifies Foundry connectivity

@app.get("/health")
async def health():
    try:
        client.ontologies.Ontology.list()
        return {"status": "healthy", "foundry": "connected"}
    except foundry.ApiError as e:
        return {"status": "degraded", "foundry": f"error_{e.status_code}"}

• Circuit breaker pattern for Foundry API calls
• Graceful degradation when Foundry is unreachable
• Timeout configuration: 30s for reads, 60s for writes
• Connection pooling configured

Monitoring & Alerting

• Metrics: request count, latency p50/p99, error rate by status code
• Alert: 5xx error rate > 5% for 5 minutes → P1
• Alert: p99 latency > 10s for 10 minutes → P2
• Alert: 429 rate > 10/min → P2 (tune rate limiter)
• Alert: 401/403 errors → P1 (credential issue)
• Dashboard with Foundry API health summary

Documentation

• Incident runbook: palantir-incident-runbook
• Credential rotation procedure documented
• Rollback procedure documented and tested
• On-call escalation path defined
• Foundry support contact info available

Deploy

set -euo pipefail
# Pre-flight
curl -sf "https://$FOUNDRY_HOSTNAME/api/v2/ontologies" \
  -H "Authorization: Bearer $FOUNDRY_TOKEN" > /dev/null \
  && echo "Foundry API reachable" || echo "BLOCKED: Foundry unreachable"

# Deploy with canary
kubectl set image deployment/my-app app=myimage:v2.0.0 --record
kubectl rollout status deployment/my-app --timeout=300s

Rollback

kubectl rollout undo deployment/my-app
kubectl rollout status deployment/my-app

Output

• Production deployment with verified Foundry connectivity
• Health checks passing
• Monitoring and alerting active
• Rollback procedure tested
