GitHub - instant-dev/instant: JavaScript API framework with ORM, migrations and vectors
instant.dev provides a fast, reliable and battle-tested ORM and migration management system for Postgres 13+ built in JavaScript. For those familiar with Ruby on Rails, instant.dev adds functionality similar to ActiveRecord to the Node.js, Deno and Bun ecosystems. We have been using it since 2016 in production at Autocode where it has managed over 1 billion records in a 4TB AWS Aurora Postgres ins
これは自作DBMSアドベントカレンダー2020、5 日目の記事です。 こんにちは、starpoz です。DBMS を作る人が増えてきたかも！という状況を後押ししたいので、自作に必要な理論の話をしてみようと思います。 はじめに DBMS 自作したいですよね！私は元々トランザクション処理 (OLTP) に興味があり、2PL (Two Phase Locking) プロトロルにおける deadlock というものが嫌で、それをなんとかしたい、という動機から OLTP についての研究開発活動を始めました。その話はまたどこかでするとして、今日は serializability (直列化可能性) よくわかりません、という人のために、できるだけ簡潔だが正しい説明を試みます。え？DBMSの自作は？？？と思ったかも知れませんが、理論を知らないと作れないので遠回りですが仕方ないのです(半分くらい嘘)。 Ser

この記事はMerpay Advent Calendar 2021 の23日目の記事です。メルペイPayment Platformチームの @foghost がお送りします。 本記事は決済システム開発の観点でリコンサイルを通して防ぎたいリスクについて説明した後、メルペイでリコンサイルについての取り組みについてご紹介します。 リコンサイルとは リコンサイルで検索するとwikipediaではリスク管理の手法の1つと書かれています。人間の様々の活動においてミスが必ず発生するので、リコンサイルはそれら活動の結果が期待通りになっているかどうかを再度確認することで、誤差を検知して様々なリスクを回避することができます。 定義だけ説明してもピンと来ない方が多いかと思いますが、実は普段の生活でも広い意味でのリコンサイルが必要となる場面が多いです。例えば以下の売店で買い物するときの流れを考えてみましょう。 お客
PostgreSQL 14 Internals
This book is for those who will not settle for a black-box approach when working with a database. Briefly touching upon the main concepts of PostgreSQL, the book then plunges into the depths of data consistency and isolation, explaining implementation details of multiversion concurrency control and snapshot isolation, buffer cache and write-ahead log, and the locking system. The rest of the book c
Local write forwarding with Amazon Aurora | Amazon Web Services
AWS Database Blog Local write forwarding with Amazon Aurora Applications designed in the cloud need to be able to scale. For stateless resources like application servers, this is a straightforward task and can be achieved by simply adding additional compute resources behind a load balancer. For stateful resources such as databases, scaling can be more challenging. With the release of Amazon Aurora

Tao of Node - Design, Architecture & Best PracticesMarch 14, 2022 • 48 minute read One of the main benefits of JavaScript is that it runs both in the browser and the server. As an engineer you need to master a single language and your skills will have a variety of applications. This is what drew me to Node in 2015 - I didn’t have to switch between languages and tech stacks. Node allows you to reus
tldr: Rust/coreutils ( https://github.com/uutils/coreutils/ ) is now available in Debian, good enough to boot a Debian with GNOME, install the top 1000 packages, build Firefox, the Linux Kernel and LLVM/Clang. Even if I wrote more than 100 patches to achieve that, it will probably be a bumpy ride for many other use cases. It is also a terrific project to learn Rust. See the list of good first bugs
