Overview
What this challenge is about.
Design 9 event types with Avro schemas for an order-to-cash pipeline. Walk through 5 failure modes. Earn a verifiable certificate.
The scenario
The distributor (around 280,000 SKUs, around 4,200 orders/day) loses around EUR 90k/month in fulfillment penalties when the OTC pipeline times out — event-driven decouples the failure modes.
The Brief
What you'll do, and what you'll demonstrate.
Design an event-driven order-to-cash architecture with explicit choreography, schema evolution, and 5 named failure-mode mitigations.
Earning criteria — what you'll demonstrate
- Design event-driven architectures with choreography vs orchestration trade-offs
- Specify Avro schemas with forward/backward-compatible evolution rules
- Apply saga patterns for distributed transactions with compensating actions
- Document architecture decisions with ADRs that survive team turnover
