Have you ever waited far too long for a MySQL query to finish and wondered if there’s a better way? If you manage a MySQL database or build apps that depend on one, you know how slow queries can grind everything to a halt. Users get frustrated, response times creep up, and suddenly you’re dealing with support tickets instead of focusing on new features. Maybe you’re seeing queries that used to fly

Agents
Intelligent agents are considered by many to be the ultimate goal of AI. The classic book by Stuart Russell and Peter Norvig, Artificial Intelligence: A Modern Approach (Prentice Hall, 1995), defines the field of AI research as “the study and design of rational agents.” The unprecedented capabilities of foundation models have opened the door to agentic applications that were previously unimaginabl
At the PGConf.dev 2025 Global Developer Conference, Bohan Zhang from OpenAI shared OpenAI’s best practices with PostgreSQL, offering a glimpse into the database usage of one of the most prominent unicorn company. At OpenAI, we utilize an unsharded architecture with one writer and multiple readers, demonstrating that PostgreSQL can scale gracefully under massive read loads. — PGConf.dev 2025, Bohan
Achieve a high-speed InnoDB purge on Amazon RDS for MySQL and Amazon Aurora MySQL | Amazon Web Services
AWS Database Blog Achieve a high-speed InnoDB purge on Amazon RDS for MySQL and Amazon Aurora MySQL Purge is a housekeeping operation in a MySQL database. The InnoDB storage engine relies on it to clean up undo logs and delete-marked table records that are no longer needed for multiversion concurrency control (MVCC) or rollback operations. While our applications pursue a database design that aims
Patterns for Building LLM-based Systems & Products [ llm engineering production 🔥 ] · 66 min read Discussions on HackerNews, Twitter, and LinkedIn “There is a large class of problems that are easy to imagine and build demos for, but extremely hard to make products out of. For example, self-driving: It’s easy to demo a car self-driving around a block, but making it into a product takes a decade.”
【速報】Rails 8.0.0がリリースされました Rails 8.0（v8.0.0タグ）は、7.2.0リリースから半年後のリリースということもあり、メジャーリリースとしてはChangelogの変更件数が少なめなのが特徴です。機能面では、Strong Parametersのexpect追加や、MySQL 5.5のサポート廃止が目につきます。大きなbreaking changesも今のところ見当たりません。 rails/rails at v8.0.0 以下、Rails 8.0のChangelogを件数の多い順に見ていきます。なお、原則として削除のChangelogは、その項目が非推奨化されたときのプルリク情報にリンクしています。 なお、以下の機能にはChangelogがありません。 Action Mailbox Action Mailer 🔗 Active Record（56件） Rail
In 2006 Microsoft conducted a customer survey to find what new features users want in new versions of Microsoft Office. To their surprise, more than 90% of what users asked for already existed, they just didn't know about it. To address the "discoverability" issue, they came up with the "Ribbon UI" that we know from Microsoft Office products today. Office is not unique in this sense. Most of us ar

Introduction to Go 1.22 The latest Go release, version 1.22, arrives six months after Go 1.21. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Changes to the language Go 1.22 makes two changes to “for” loops. Previous
I am starting this new year the same way I ended the last: taking antibiotics because my biological daughter brought home a nasty sinus bug from Carnegie Mellon’s preschool. This was after my first wife betrayed me and gave me COVID. Nevertheless, it is time for my annual screed on last year’s major database happenings and trends since a lot has happened. My goal is to keep my trenchant opinions f
Incremental models are one of the most powerful features of dbt. Let’s review common patterns for implementing incrementals.

These macros output text and are identi

Back to homepage Nowadays the most popular programming languages are Python, Javascript, Java, C++, C#, Kotlin and Ruby, and the average programmer is probably familiar with one or more of these languages. It's relatively easy to switch from one to another (barring any framework specific knowledge that may be needed), since they are all imperative (and for the most part object-oriented) languages,
Concurrency is not very intuitive. You need to train your brain to consider what happens when multiple processes execute a certain code block at the same time. There are several issues I often encounter: Failing to recognize potential concurrency issues: It's not uncommon for both beginner and seasoned developers to completely miss a potential concurrency problem. When this happens, and the concur

The In-depth Guide to ActiveRecord load_async in Rails 7 Updated Mar 1, 2022 17 minute read Rails 7 introduces ActiveRecord load_async method that runs SQL queries asynchronously in the background thread. This seemingly simple change of just adding a single new method that takes no arguments has profound implications for database layer interactions. In this tutorial, we’ll deep dive into the intri

"Get or create" is a very common operation for syncing data in the database, but implementing it correctly may be trickier than you may expect. If you ever had to implement it in a real system with real-life load, you may have overlooked potential race conditions, concurrency issues and even bloat! In this article I explore ways to "get ot create" in PostgresSQL. Illustration by Abstrakt Design Ta
I’ve been working professionally for the better part of a decade on web apps and, in that time, I’ve had to learn how to use a lot of different systems and tools. During that education, I found that the official documentation typically proved to be the most helpful. Except…Postgres. It’s not because the official docs aren’t stellar (they are!)–they’re just massive. For the current version (17 at t

Sketch of a Post-ORM
I’ve been writing a lot of database access code as of late. It’s frustrating that in 2023, my choices are still to either write all of the boilerplate by hand, or hand all database access over to some inscrutable “agile” ORM that will become a crippling liability in the 2-3y timescale. This post is about how I want to use databases, from the perspective of an application server developer—not a DBA
After a few months of research and experimentation with running a heavily DB-dependent Go app, we’ve arrived at the conclusion that sqlc is the figurative Correct Answer when it comes to using Postgres (and probably other databases too) in Go code beyond trivial uses. Let me walk you through how we got there. First, let’s take a broad tour of popular options in Go’s ecosystem: database/sql: Go’s b
Updated 2024-09-17 to reflect updated PgBouncer support for protocol-level prepared statements 🐘 To start, I want to say that I’m appreciative that PgBouncer exists and the work its open source maintainers put into it. I also love working with PostgreSQL, and I’m thankful for the incredible amount of work and improvements that go into it as well. I also think community and industry enthusiasm aro
Django for Startup Founders: A better software architecture for SaaS startups and consumer apps
In an ideal world, startups would be easy. We'd run our idea by some potential customers, build the product, and then immediately ride that sweet exponential growth curve off into early retirement. Of course it doesn't actually work like that. Not even a little. In real life, even startups that go on to become billion-dollar companies typically go through phases like: Having little or no growth fo
Java Interview Questions
Java remains one of the most common and popular programming languages in the world because of its strong features. Therefore, it’s no surprise that good Java programmers are very much sought after by almost all organizations across the world – be it startups or large multinational corporations. Considering the above, we created a list of common job interview questions about Java programming with d
