Can I use this for real-time data pipelines?

Yes, the skill includes specialized guidance for high-throughput event streaming, message routing, and implementing reactive systems using brokers like Apache Kafka.

What is the difference between choreography and orchestration in sagas?

Choreography uses decentralized events where each service reacts to events from others, while orchestration uses a central coordinator to manage the workflow and direct services.

How does this skill help with eventual consistency?

It provides patterns for managing state across distributed services, including idempotent message handling, conflict resolution strategies, and building read projections from event streams.

When should I use CQRS?

CQRS is best used when there is a high read-to-write ratio, complex query requirements, or when the read and write operations need to scale independently using different data models.

API Development

Facilitates the design and implementation of scalable, distributed systems using event-driven patterns like CQRS, event sourcing, and sagas.

About

This skill provides expert guidance for architecting resilient distributed systems that communicate through asynchronous events. It assists developers in implementing complex patterns such as Event Sourcing for auditability, CQRS for high-performance read/write separation, and Sagas for managing distributed transactions across microservices. By focusing on loose coupling and eventual consistency, it helps build systems that are highly scalable, maintainable, and capable of handling complex real-time data flows using industry-standard message brokers.
