Why MySQL Discourages UUID as Primary Key: Performance Comparison with Auto‑Increment and Random Keys

This article investigates MySQL's recommendation against using UUIDs or non‑sequential keys as primary keys by creating three tables, benchmarking insert and query speeds with Spring Boot/JdbcTemplate, analyzing index structures, and discussing the trade‑offs of auto‑increment, UUID, and random long keys.

MySQL Query Optimization Techniques: LIMIT, Implicit Conversion, Joins and More

The article shows how common MySQL performance pitfalls—such as large LIMIT offsets, implicit type conversions, sub‑query‑based updates or deletes, mixed ORDER BY, EXISTS clauses, and misplaced predicates—can be rewritten into index‑friendly forms using filters, joins, early limits, UNION ALL, and CTEs to achieve execution times that drop from seconds to milliseconds.

Implementing Dynamic MySQL Master‑Slave Switching in SpringBoot Using AOP and Custom Annotations

This article explains how to use SpringBoot, AOP, and a custom @DataSource annotation to dynamically switch between MySQL master and slave databases, automatically falling back to the master when a slave fails, thereby achieving high availability for backend services.

How to Interpret the rows Value in MySQL EXPLAIN Output

This article explains what the rows column in MySQL EXPLAIN means, demonstrates three situations—when a small rows value indicates good performance, when it does not, and when rows is misleading—using concrete SQL examples, force‑index tricks, and multi‑table join analyses to show why rows alone cannot reliably judge query efficiency.
