    Project mention: Does anyone know any good java implementations for distributed key-value store? | /r/ExperiencedDevs | 2023-06-08

  • Quasar

    Fibers, Channels and Actors for the JVM (by puniverse)

    Project mention: Java 21 makes me like Java again | | 2023-09-16

    Java 21 doesn't retrofit green threads though. Quasar [0] is a library that implemented fibers for Java and the main developer pron has joined the OpenJDK development team. All that was necessary for first party support is to make the JDK libraries yield when blocking.

    Adopting async isn't impossible at all, there is very little demand for it.
