Top 10 Java Concurrency Projects

  • GitHub repo Disruptor

    High Performance Inter-Thread Messaging Library

    Project mention: Bevy's First Birthday: a year of open source Rust game engine development | | 2021-08-10

    For mapping a complicated a graph onto a set of cores the closest thing I know of is the distruptor pattern. I am curious whether or not you would consider it to be a job scheduler.

  • GitHub repo Vert.x

    Vert.x is a tool-kit for building reactive applications on the JVM

    Project mention: Async I/O for Dummies (2018) | | 2021-12-05

    Backend newb, here. I have a dumb question - can someone give me a summary, or blog post to a summary, of the pros /cons of async versus threads?

    One thing I have been using as a way of understanding hi-perf backends is analyzing why the vert.x framework [1] (and its underlying server, netty) does so well on benchmarks [2], but as newb, I do not think I would get a lot form that exercise without a little hand holding.

  • GitHub repo react-native-threads

    Create new JS processes for CPU intensive work

    Project mention: React Native: Understanding Threads. | | 2021-10-17

    In React Native, every process has only one thread. Unfortunately, because of this, people often use the terms interchangeably. You’ll notice UI Thread, JS Thread, and React Native Modules Thread are actually all processes, and react-native-threads actually implements multi-processing.
