The article examines why major Chinese cloud and technology providers are building distributed, cloud‑native or HTAP databases on PostgreSQL instead of MySQL, detailing differences in data types, sequences, extensions, monitoring, replication, licensing, and MVCC implementation.
This guide explains how to route Google traffic, set system and Chrome languages to English, and edit Chrome's Local State file on macOS using terminal commands so that the Gemini AI chatbot becomes available directly within Chrome.
This article reveals eight powerful, lesser‑known MySQL 8.0 features—including window functions, descending indexes, generated columns, invisible indexes, optimizer hints, resource groups, LATERAL JOIN, and multi‑valued JSON indexes—showing how they dramatically improve query performance and simplify complex SQL tasks.
The article examines why major Chinese cloud providers and enterprises are building PostgreSQL‑based distributed, cloud‑native databases instead of MySQL, detailing PostgreSQL's richer data types, native sequence support, extensible ecosystem, advanced replication, licensing advantages, and MVCC implementation, while also noting MySQL's remaining strengths.
Using SELECT * in MySQL queries increases disk I/O, inflates network traffic, and prevents the optimizer from using covering indexes, leading to slower performance and unnecessary resource consumption.
