The database world is full of hype and marketing fog. This column cuts through it with blunt commentary, case studies, and technical deep dives.

A whole generation of developers has been told “cloud-first.” This column collects data, case studies, and commentary on the real economics—and traps—of public cloud rental models.

A conversation between Mike Stonebraker (MIT CSAIL, Turing Award Winner, Creator of PostgreSQL), Andy Pavlo (Carnegie Mellon University), and the DBOS team.

MySQL is to the internet what baijiu is to China: harsh, hard to swallow, yet worshipped because culture demands obedience. Both are loyalty tests—will you endure discomfort to fit in?

VictoriaMetrics/Logs replace Prometheus/Loki for 10x observability performance, Vector handles logs, unified UI, firewall/SELinux/credential hardening.

VictoriaMetrics is brutally efficient—using a fraction of Prometheus + Loki’s resources for multiples of the performance. Pigsty v4 swaps to the Victoria stack; here’s the beta for anyone eager to try it.

MinIO just entered maintenance mode. What replaces it? Can RustFS step in? I tested the contenders so you don’t have to.

Dec 4, 2025, Taobao, Alipay, and Xianyu all cratered. Users got charged while orders still showed “unpaid,” a carbon copy of the 2024 Double-11 fiasco.

MinIO announces it is entering maintenance mode, the dragon-slayer has become the dragon – how MinIO transformed from an open-source S3 alternative to just another commercial software company

PostgreSQL 18 becomes the default version, EL10 and Debian 13 support added, extensions reach 437, and Pigsty wins the PostgreSQL Magneto Award.

Your ability to ask questions—and your taste in what to ask—determines your position in the AI era. When answers become commodities, good questions become the new wealth. We are living in the moment this prophecy comes true.

Context window economics, the polyglot persistence problem, and the triumph of zero-glue architecture make PostgreSQL the database king of the AI era.

PostgreSQL already won. The real battle is the distro layer. Will Chinese developers watch from the sideline or craft a PG “Ubuntu” for the world?

In serious production you can’t rely on an upstream that explicitly says “no guarantees.” When someone says “don’t count on me,” the right answer is “then I’ll run it myself.”

Tons of users running the official docker postgres image got burned during recent minor version upgrades. A friendly reminder: think twice before containerizing production databases.

A ClickHouse permission tweak doubled a feature file, tripped a Rust hard limit, and froze Cloudflare’s core traffic for six hours—their worst outage since 2019. Here’s the full translation plus commentary.

Free, open, no VPN. Install PostgreSQL and 431 extensions on 14 Linux distros × 6 PG versions via native RPM/DEB—and a tiny CLI.

Founders here get asked the same question over and over: what if Alibaba builds the same thing? Alicloud RDS just launched Supabase as a managed service. Exhibit A.

AWS finally published the Oct 20 us-east-1 postmortem. I translated the key parts and added commentary on how one DNS bug toppled half the internet.

us-east-1’s DNS control plane faceplanted for 15 hours and dragged 142 AWS services—and a good chunk of the public internet—down with it. Here’s the forensic tour.

PostgreSQL official repos cut off global mirror sync channels, open-source binaries supply disrupted, revealing the true colors of various database and cloud vendors.

The second edition of Designing Data-Intensive Applications has released ten chapters. I translated them into Chinese and rebuilt a clean Hugo/Hextra web version for the community.

The same forces that once led MongoDB and MySQL toward closure are now at work in the PostgreSQL ecosystem. The PG world needs a distribution that represents “software freedom” values.
