Known Limitations & Mitigations

Limitation 1: Vector Database Size

Description: Milvus configured for 1M embeddings Impact: After 1M solutions stored, performance degradation expected Mitigation: Archive old solutions, implement sharding strategy Timeline: Expected after 2 years of operation (assuming 1,300 solutions/day)

Limitation 2: LiteLLM Token Cost

Description: Using GPT-3.5-turbo at ~$0.001 per 1K tokens Impact: $0.02-0.05 per ticket analysis (depending on ticket size) Mitigation: Implement token budget limits, use cheaper models for simple issues Timeline: Monitor costs after first 30 days

Limitation 3: Workflow Parallelization

Description: n8n free tier limited to 5 concurrent workflows Impact: High-volume scenarios (>5 simultaneous tickets) will queue Mitigation: Upgrade to n8n Pro for unlimited parallelization Timeline: Evaluate after first month of operation

Limitation 4: Email Delivery Reliability

Description: Email sending depends on Freescout's mail provider Impact: Email delivery may be delayed 5-30 minutes Mitigation: Implement retry logic in Workflow B, notify users of delays Timeline: Standard limitation of email infrastructure

Risk Assessment & Mitigation

High Risk: Infrastructure Failure

Risk: Docker containers crash Impact: System offline, tickets not processed Mitigation:

  • Implement container restart policies
  • Set up monitoring alerts
  • Create incident response runbook
  • Weekly health check automation

High Risk: Data Loss

Risk: PostgreSQL or Milvus loses data Impact: Knowledge base lost, audit trail incomplete Mitigation:

  • Daily automated backups
  • Off-site backup storage
  • Recovery time objective (RTO): 1 hour
  • Recovery point objective (RPO): 1 day

Medium Risk: Performance Degradation

Risk: Vector search becomes slow Impact: Workflow C takes >10 minutes Mitigation:

  • Monitor search latency
  • Implement caching strategy
  • Archive old vectors quarterly

Medium Risk: API Rate Limiting

Risk: LiteLLM or Freescout API rate limits exceeded Impact: Workflow processing delays Mitigation:

  • Implement request queuing
  • Add retry with exponential backoff
  • Monitor API quota usage

Low Risk: Integration Breaking Changes

Risk: Freescout API updates incompatibly Impact: Webhook receivers or API calls fail Mitigation:

  • Subscribe to API changelog
  • Implement API versioning
  • Quarterly integration testing
