  • Seastar

    High performance server-side application framework

    Project mention: How much reason is there to be multi-threaded in the k8s environment | /r/scala | 2023-07-04

    b) It's proven now e.g Seastar, Glommio that the fastest way to run a multi-threaded application is to have one instance with one thread pinned per CPU core. Then to have fibers/lightweight threads on top handling all of the asynchronous code. Your approach of lots of instances is the slowest so there will be a ton of unnecessary thread context-switching.

  • C++ REST SDK

    The C++ REST SDK is a Microsoft project for cloud-based client-server communication in native code using a modern asynchronous C++ API design. This project aims to help C++ developers connect to and interact with services.

    Project mention: What is the industry standard today in C++ to deploy REST microservices in Kubernetes? | /r/cpp | 2023-09-06

    My favourite was Microsoft's cpprestsdk, but for some reason now is in maintenance mode, I don't know why, so it's hard to suggest it for new projects. A nice alternative is restc-cpp, that's has a good high-level interface, if this is what you want.

  • InfluxDB

    Collect and Analyze Billions of Data Points in Real Time. Manage all types of time series data in a single, purpose-built database. Run at any scale in any environment in the cloud, on-premises, or at the edge.

  • C++ Actor Framework

    An Open Source Implementation of the Actor Model in C++

    Project mention: C++ Jobs - Q3 2023 | /r/cpp | 2023-07-04


  • cppcoro

    A library of C++ coroutine abstractions for the coroutines TS

    Project mention: Struggle with C++ 20 Coroutines | /r/cpp_questions | 2023-05-13

    PS: Take a look at cppcoro; this might help as well, especially generator<>, if you're looking to generate numbers, and stuff;

  • userver

    The C++ Asynchronous Framework

    Project mention: Rust vs Go/JVM: dev speed + safety in practice | /r/rust | 2023-06-25

    They recently open sourced internal framework: https://github.com/userver-framework/userver

  • c-ares

    A C library for asynchronous DNS requests

    Project mention: Windows DNS with CNAME not resolving | /r/sysadmin | 2023-05-28

    I found that ... https://github.com/c-ares/c-ares/pull/93

  • CppServer

    Ultra fast and low latency asynchronous socket server & client C++ library with support TCP, SSL, UDP, HTTP, HTTPS, WebSocket protocols and 10K connections problem solution

  • quill

    Asynchronous Low Latency C++ Logging Library (by odygrd)

    Project mention: quill v2.7.0 released - Asynchronous Low Latency C++ Logging Library | /r/u_Junior-Homework-4581 | 2023-02-06
  • G3log

    G3log is an asynchronous, "crash safe", logger that is easy to use with default logging sinks or you can add your own. G3log is made with plain C++14 (C++11 support up to release 1.3.2) with no external libraries (except gtest used for unit tests). G3log is made to be cross-platform, currently running on OSX, Windows and several Linux distros. See Readme below for details of usage.

  • continuable

    C++14 asynchronous allocation aware futures (supporting then, exception handling, coroutines and connections)

    Project mention: SAF, a scheduler aware future/promise (in the Asio ecosystem) | /r/cpp | 2022-12-21

    cool. how does this compare to https://naios.github.io/continuable/ ?

  • ext-openswoole

    Programmatic server for PHP with async IO, coroutines and fibers

    Project mention: [Blog] Unlocking the power of asynchronous PHP 💪 | /r/platform_sh | 2023-05-24

    One such promising solution is Swoole, a high-performance networking framework that helps PHP applications handle server-side tasks more effectively.

  • helio

    A modern framework for backend development based on io_uring Linux interface

  • qcoro

    C++ Coroutines for Qt

    Project mention: Qt Creator 10 Released | news.ycombinator.com | 2023-03-29

    You're not completely wrong, but I think this overstating things by a lot. I'll grant you the containers for example, but you can generally use STL algorithms with them. And plenty of old ways of doing things have left modern Qt-based codebases and moved to more modern ways of doing things, including a fair amount of moc macro usage (and yes, you can remove the moc these days, but it has different perf characteristics - cf. the verdigris project).

    The community around Qt is pretty active at adopting modern C++, e.g. imho https://github.com/danvratil/qcoro is leading work.

  • YACLib

    Yet Another Concurrency Library

  • mysql

    MySQL C++ client based on Boost.Asio (by boostorg)

  • idle

    Project mention: Scriptable Headless Player Bots and independent ECS in a Custom UE C++ Server for MMO(RPG)s. | /r/unrealengine | 2022-10-10
  • redis

    An async redis client designed for performance and scalability (by boostorg)

    Project mention: Build Your Own Redis with C/C++ | news.ycombinator.com | 2023-03-18

    [2] https://github.com/boostorg/redis/issues/53

  • node-gdal-async

    Node.js bindings for GDAL (Geospatial Data Abstraction Library) with full async support

    Project mention: GeoPicker | dev.to | 2023-01-25

    Geospatial dataset picker via fast http rest interface written in NodeJs for GDAL bindings and Fastify

  • packio

    An asynchronous msgpack-RPC and JSON-RPC library built on top of Boost.Asio.

    Project mention: Asio is great if you’re building a library/application with non-Asio API. But building Asio APIs using async compositions is too messy. Anybody else agree ? | /r/cpp | 2022-12-23

    That's not even helpful, as you usually read/write using composed ops and they will interleave anyway. To have an io object that's capable of correctly pipelining multiple concurrent write- or read-operations, you need a custom strand like this: https://github.com/qchateau/packio/blob/master/include/packio/internal/manual_strand.h
