  1. Music the style of simultaneously combining a number of parts, each forming an individual melody and harmonizing with each other.
  2. Programming a Ruby gem for concurrent programming focusing on performance and developer happiness.

What is Polyphony

Polyphony is a library for building concurrent applications in Ruby. Polyphony harnesses the power of Ruby fibers to provide a cooperative, sequential coroutine-based concurrency model. Under the hood, Polyphony uses libev as a high-performance event reactor that provides timers, I/O watchers and other asynchronous event primitives.

Features

  • Co-operative scheduling of concurrent tasks using Ruby fibers.
  • High-performance event reactor for handling I/O events and timers.
  • Natural, sequential programming style that makes it easy to reason about concurrent code.
  • Abstractions and constructs for controlling the execution of concurrent code: supervisors, cancel scopes, throttling, resource pools etc.
  • Code can use native networking classes and libraries, growing support for third-party gems such as pg and redis.
  • Use stdlib classes such as TCPServer, TCPSocket and OpenSSL::SSL::SSLSocket.
  • Competitive performance and scalability characteristics, in terms of both throughput and memory consumption.

Documentation
