Event Sourcing Pattern

[Content coming soon - explains event sourcing architecture, state reconstruction, and event-driven workflows]

Overview

Event sourcing records every state change as an immutable event:

Event Stream:
1. "Job 'test-suite' started at 15:32"
2. "All unit tests passed in 45s"
3. "Coverage: 92%"
4. "Artifact deployed to S3"
→ Current State: Job successful

Benefits

  • Complete audit trail
  • Temporal queries ("what was state at 15:35?")
  • Event replay and recovery
  • Event-driven workflows
