Saga Choreography Design

Saga Choreography Design governs event-driven saga, shaping system behavior under specific failure modes and workloads.

architecture

Definition

Saga Choreography Design is a design property concerning event-driven saga. It defines how the system behaves under specific conditions — what guarantees hold, what trade-offs apply, and how the mechanism interacts with related techniques. The property is only meaningful when its preconditions are met; outside those conditions it provides no benefit and may add cost.

Context and scope

Apply Saga Choreography Design when designing systems where event-driven saga matters. It is most useful under partial failure, high load, or correctness requirements. Pair it with observability to verify the claimed behavior in production. Do not assume the property holds without testing the specific configuration and workload.

Common misconceptions

  • Saga Choreography Design eliminates all problems in its domain — it only bounds or shapes specific failure modes, not all pathologies.
  • Saga Choreography Design is free once you adopt the right tool — the property depends on configuration, workload, and failure pattern, not the product label alone.

Anti-patterns

  • Enabling Saga Choreography Design without measuring its cost in latency, availability, or operational complexity under production-like conditions.
  • Assuming Saga Choreography Design composes safely with other guarantees — combining mechanisms can introduce new failure modes or negate benefits.
