Sogou Workflow

Powers Sogou's core services handling over 10 billion daily requests, demonstrating reliability in high-concurrency production environments as stated in the README.

Integrates networking, computation, and file IO tasks into a single workflow with support for series, parallel, and DAG structures, simplifying complex asynchronous programming.

Uses C++11 standard without relying on boost or asio, making it self-contained and easier to integrate, as highlighted in the compiling requirements.

Abstracts tasks into five types with factory generation and explicit lifecycle management, reducing callback depth and memory leaks without std::shared_ptr.
