What problem does it solve?

This Skill ensures your data processing pipelines remain operational even when downstream services are unavailable by implementing a circuit breaker pattern with multiple fallback mechanisms.

Core Features & Use Cases

• Resilient API Calls: Gracefully handles failures from primary and secondary APIs.
• Data Fallback: Stores data locally or sends to a Kafka topic when primary destinations fail.
• Use Case: An e-commerce order processing system needs to enrich order data with customer information from a primary API. If that API is down, the system can fall back to a secondary API, then to a local cache, and finally log the failed attempt to a dead-letter queue, ensuring no data is lost and the system remains responsive.

Quick Start

Run the circuit breaker pipeline with sample data using the provided shell script.
