Polyphony - Fine-Grained Concurrency for Ruby
Polyphony | pəˈlɪf(ə)ni |
- Music the style of simultaneously combining a number of parts, each forming an individual melody and harmonizing with each other.
- 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
andredis
. - Use stdlib classes such as
TCPServer
,TCPSocket
andOpenSSL::SSL::SSLSocket
. - Competitive performance and scalability characteristics, in terms of both throughput and memory consumption.
