LittleHorse

LittleHorse is a high-performance microservice orchestration engine that allows developers to build scalable, maintainable, and observable applications. By allowing LittleHorse to manage coordination and sequencing of your applications, you no longer have to worry about:

• Wiring microservices together with RPC calls or message queues.
• Retries, timeouts, dead-letter queues.
• Distributed tracing and debugging across multiple microservices.
• Scheduling actions to asychronously happen in the future.
• Backpressure and scalability.

Running Your First Workflow

To run a workflow with LittleHorse, you need to:

• Define tasks which are units of work that can be used in a process, and implement programs that execute those tasks.
