サーバーレスサービスである API Gateway や Lambda を使って 同期的な REST API を構築されている方は多いのではないでしょうか。サーバーレスで REST APIをつくると、リクエストの分だけの課金であったり、デフォルトの可用性が与えられたりメリットは大きいです。ただし、サーバーレスの真価は非同期アーキテクチャにあります。このセッションではさまざまなサーバーレスの非同期パターンを紹介するとともに、実際の顧客事例においてどのようなユースケースで非同期系サーバーレスが利用されているかをご紹介いたします。

We are pleased to announce the 1.0 release of Tokio, an asynchronous runtime for the Rust programming language. Tokio provides the needed building blocks for writing reliable networking applications without compromising speed. It comes with asynchronous APIs for TCP, UDP, timers, a multi-threaded, work-stealing scheduler, and more. Over the years, we have been delighted watching our users build am
Making the Tokio scheduler 10x fasterOctober 13, 2019 We've been hard at work on the next major revision of Tokio, Rust's asynchronous runtime. Today, a complete rewrite of the scheduler has been submitted as a pull request. The result is huge performance and latency improvements. Some benchmarks saw a 10x speed up! It is always unclear how much these kinds of improvements impact "full stack" use
14 Linting Rules To Help You Write Asynchronous Code in JavaScript
Debugging asynchronous code in JavaScript can feel like navigating a minefield at times. You don't know when and where the console.logs will print out, and you have no idea how your code is executed. It's hard to correctly structure async code so it executes in the right order as you intend it to. Wouldn't it be nice if you had some guidance while writing asynchronous code, and to get a helpful me
Last year, we launched HTMLRewriter for Cloudflare Workers, which enables developers to make streaming changes to HTML on the edge. Unlike a traditional DOM parser that loads the entire HTML document into memory, we developed a streaming parser written in Rust. Today, we’re announcing support for asynchronous handlers in HTMLRewriter. Now you can perform asynchronous tasks based on the content of
Tokio is an asynchronous runtime for the Rust programming language. It provides the building blocks needed for writing networking applications. It gives the flexibility to target a wide range of systems, from large servers with dozens of cores to small embedded devices. At a high level, Tokio provides a few major components: A multi-threaded runtime for executing asynchronous code. An asynchronous
What is asynchronous communication? Plus, how to implement it
What the heck is asynchronous communication anyway? And what you can do to start implementing it, whether you're an individual contributor or a team leader. Illustration by Yin WeihungStudy after study after study into remote work has clarified that remote workers are more productive than their office-bound counterparts. What’s not entirely clear is why. Yes, people gain back time (and sanity) by

What This Book Covers This book aims to be a comprehensive, up-
In 2017, I said that “asynchronous Rust programming is a disaster and a mess”. In 2021 a lot more of the Rust ecosystem has become asynchronous – such that it might be appropriate to just say that Rust programming is now a disaster and a mess. As someone who used to really love Rust, this makes me quite sad. I’ve had a think about this, and I’m going to attempt to explain how we got here. Many peo
Today, we, the Tokio team, are announcing the initial release of Tokio Console (Github), enabling Rust developers to gain deeper insight into the runtime behavior of their applications. And just like that, we get to peek under the hood. —niedzejkob Tokio Console is a diagnostics and debugging tool for asynchronous Rust programs. It gives you a live, easy-to-navigate view into the program's tasks a

This week I was debugging a misbehaving Python program that makes significant use of Python’s asyncio. The program would eventually take very long periods of time to respond to network requests. My first suspicion was a CPU-heavy coroutine hogging the thread, preventing the socket coroutines from running, but an inspection with pdb showed this wasn’t the case. Instead, the program’s author had mad

Using asynchronous web APIs from WebAssembly Stay organized with collections Save and categorize content based on your preferences. The I/O APIs on the web are asynchronous, but they're synchronous in most system languages. When compiling code to WebAssembly, you need to bridge one kind of APIs to another—and this bridge is Asyncify. In this post, you'll learn when and how to use Asyncify and how
Asynchronous Ruby
Applications that process many simultaneous requests are an area where Ruby struggles. The traditional request-per-process/thread model does not scale well. Explicit concurrency, including promises/futures, impose a significant cognitive burden and their use pollutes code all the way up the call chain. We present async, a gem for Ruby that implements the reactor pattern using stackful coroutines (

Error boundaries are React components that catch JavaScript errors anywhere in their child component tree, log those errors, and display a fallback UI instead of the component tree that crashed. Take this example: If we run this code, the ErrorBoundary will catch the error, render the fallback UI (Something went wrong) and log

Asynchronous streams in Rust (part 1) - Futures, buffering and mysterious compilation error messages | Blog | Guillaume Endignoux
If you are already reading my blog, you may have noticed that I see a lot of potential in the Rust programming language. The safety and efficiency properties of Rust make it the programming language of “fearless concurrency”, and in particular the async/.await syntax that was stabilized about a year ago really make asynchronous programming a core feature of Rust. The downside of this new asynchron

When we began working on Dolt we made the decision to build on top of Noms. Noms stores data in a content addressable DAG, and has countless applications. It was a great starting point for us to build Dolt, and it let us hit the ground running. Once we had a working prototype of the product we began importing data. Every dataset we imported taught us something new about the product. It helped us f

The evolution of asynchronous programming in JavaScript - LogRocket Blog
Introduction By design, JavaScript is single-threaded, which means that it can only handle one operation at a time. Because there is a single execution thread for our program to run, a question then arises: How do we go about executing a long-running operation without blocking the thread of execution? Well, welcome to asynchronous programming. Asynchronous programming in JavaScript offers a great

If you have a business no matter how small, you are collecting data, and you need to have your data accessible to make informed decisions about how to make your business better. The more successful you become the more data you are producing and the more you become dependent by it. This is when you start to realize your must have your data in a safe place like a database instead some spreadsheet. B
Announcing Tokio 0.2 and a Roadmap to 1.0November 26, 2019 We are very excited to announce Tokio 0.2. This is a ground up rework of Tokio based on async / await and experience gained over the past three years.

This release provides asynchronous File operations, and we will be adding support for more operations in subsequent releases. To use tokio-uring, first, add a dependency on the crate: tokio-uring = "0.1.0" Then, st
How to Use Multiple GitHub Accounts Git is a popular tool for version control in software development. It is not uncommon to use multiple Git accounts. Correctly configuring and switching Git accounts is challenging. In this article, we show what Git provides for account configuration, its limitations, and the solution to switch accounts automatically based on a project parent directory location.
It’s an exciting time for GUI in Rust. There are now quite a few, well written windowing libraries in Rust. winit is the leader of the pack, with the best platform support and a newly merged keyboard support PR that positions it to become the dominant windowing system in the ecosystem. There are a couple of other contenders, but none of them are serious contenders. Nowadays there’s a pretty good i
In 2013, I discovered the Rust programming language and quickly decided to learn it and make it my main programming language. In 2017, I moved to Berlin and joined Parity as a Rust developer. The task that occupied my first few months was to build rust-libp2p, a peer-to-peer library in asynchronous Rust (~89k lines of code at the moment). Afterwards, I integrated it in Substrate (~400k lines of co
