Workflow
Workflow is an asynchronous C++ task engine designed for building distributed systems and high-performance network services. It provides a framework for orchestrating complex sequences of network, file, and computational operations, allowing developers to compose these tasks into parallel workflows.
The library functions as a toolkit for implementing scalable servers and clients for protocols such as HTTP, Redis, MySQL, and Kafka. It distinguishes itself through a task-based concurrency model that manages non-blocking operations and coordinates service discovery, load balancing, and traffic routing to maintain consistent performance across distributed environments.
The system utilizes a protocol-agnostic communication layer and event-driven input/output multiplexing to handle high-volume data exchange. By structuring operations as directed acyclic graphs, the framework ensures that dependent tasks trigger automatically upon the completion of upstream data requirements, while zero-copy buffer management minimizes overhead during serialization.
