Risk Assessment

Production Blockers: NONE

Medium Risk Issues (Non-Blocking)

  1. Prometheus Metrics Not Implemented

    • Mitigation: Implementation guide provided
    • Workaround: Use structured logs
    • Timeline: Before GA release

  2. Unwrap Calls in Production Code

    • Mitigation: Most are on infallible operations
    • Workaround: Comprehensive testing
    • Timeline: Next patch release

Low Risk Issues

  1. Audit logging not comprehensive (can add post-deployment)
  2. JSON logging requires configuration (documented)

Deployment Recommendation

Strategy: Gradual Rollout

Phase 1: Canary (10% traffic, 24 hours)

  • Monitor: Error rates, latency, resource usage
  • Validate: Query speedup, refresh success

Phase 2: Expansion (50% traffic, 48 hours)

  • Continue monitoring
  • Tune configuration

Phase 3: Full Rollout (100% traffic)

  • Complete deployment
  • Document learnings

Rollback Plan

  • RTO: <5 minutes (complete rollback)
  • RPO: Last successful refresh
  • Procedure: Feature flag to 0%, pause maintenance

Key Metrics to Monitor

Critical Metrics

  • Active view count: 0-200 (max configured)
  • Storage usage: <80% warning, <90% critical
  • Refresh success rate: >99.5%
  • Query speedup: 10x-50x for aggregations

Performance Metrics

  • Candidate generation time: <1s
  • View refresh duration: <500ms (p95)
