What problem does it solve?

This Skill provides expert guidance for implementing distributed sagas in a Rust-based environment, enabling safe multi-aggregate coordination, compensation flows, and orchestration patterns across services.

Core Features & Use Cases

• Saga pattern design: Reducer-style state machines that coordinate local transactions across aggregates.
• Compensation & idempotency: Patterns to rollback or compensate when steps fail, with idempotent handling and retries.
• Event-bus integration: Techniques for publish/subscribe communication (e.g., Redpanda/Kafka) between services and sagas.
• Use Case: Orchestrate an Order → Payment → Inventory flow with centralized compensation in case of failures.

Quick Start

Start by outlining your saga state definitions and the events that drive transitions; then implement a reducer that updates state and emits next-step commands via an event bus.
