    Project mention: Concurrent Data-structure Design Walk-Through | dev.to | 2023-08-22

    There are no tests! There are various ways to test concurrent data structures. You could use a stress test, where you spawn a lot of threads and let them mutate the map in a random way and then check the consistency of the map and some invariants. You could learn TLA+ and write a formal model of the map and then verify it.

  • GS Collections

  • cicada

    🚀 Fast lightweight HTTP service framework. (by TogetherOS)

  • DSL-JSON

    High performance JVM JSON library

    Project mention: The Newest Java Json Benchmark Results just dropped | /r/java | 2023-05-01

    Afaik dsl-json came up with a lot of improvements and inspired a several other libraries like JsonIter and jsonIter-scala. Jsoniter-scala by u/plokhotnyuk is probably the most optimized JSON library on the JVM at this point, and seems to power most of the Scala ecosystem. Some implementations/optimizations eventually made their way back into Jackson and other libraries.

  • HPPC

    High Performance Primitive Collections for Java

  • linstor-server

    High Performance Software-Defined Block Storage for container, cloud and virtualisation. Fully integrated with Docker, Kubernetes, Openstack, Proxmox etc.

    Project mention: Longhorn alternatives | /r/kubernetes | 2023-01-13

    Tbf that isn't distributed storage. You could use DBRD with ZFS over it though, to accomplish this. I plan to try it at some point - I love ZFS, and for my NAS and backup target it's terrific, but I want something that can distribute across my three compute nodes.
