Production Query Lags, Developer Points to "Small Limit"
Production database queries are running slow. A developer says a small 'LIMIT' clause might be the problem. Find out why this happens and how to fix it.

Production database queries are now running much slower. This is because a small 'LIMIT' command in the code might be causing the database to do more work.

Database performance problems are rarely about one slow query.
They are about patterns you don’t see until production.
In this article, I show how to inspect real PostgreSQL behavior from a Quarkus app using pg_stat_statements, hypopg, and a PostgreSQL MCP server connected through IBM Bob.
No dashboards. No guesswork. Real data, real feedback loops.

Khi dùng NAS (RAID5) cho DB SQL trong Docker/Portainer Swarm, dữ liệu dễ bị lỗi & trễ phản hồi. Lệnh mới: bỏ Swarm, tìm giải pháp lưu trữ SQL an toàn, đảm bảo sao lưu và phục hồi nhanh. Cần mẹo từ DevOps?

Most PostgreSQL developers know "there's some TOAST thing for big values," but very few can explain how it actually works.
I just published a deep dive on PostgreSQL TOAST: how it handles the 8KB page constraint, when compression kicks in, and practical strategies for tuning large JSON/TEXT/BYTEA storage.
Covers EXTENDED/EXTERNAL/MAIN storage, monitoring TOAST growth, and avoiding hidden rewrites.

Deep dive into PostgreSQL's TOAST (The Oversized-Attribute Storage Technique) mechanism and how it works around the fundamental 8KB block size limitation. Learn when TOAST activates, how it stores large values, and the performance implications for your database design.
