CynosDB Architecture and Optimization: A PostgreSQL-Compatible NewSQL Database

CynosDB, Tencent’s PostgreSQL‑compatible NewSQL service, separates compute and storage, uses a log‑based distributed CynosStore with idempotent logs, offloads CRC checks, and implements async table extension, eliminating full‑page writes and dirty‑page flushing to deliver scalable, cost‑effective performance while preserving PostgreSQL features.
