apache/shardingsphere：README 來源編輯指南

apache/shardingsphere 的 README 將專案描述為「Empowering Data Intelligence with Distributed SQL for Sharding, Scalability, and Security Across All Databases.」。本文只整理倉庫可直接核對的內容，不把 star、Fork 或宣傳語當成品質證明。README 在「Apache ShardingSphere - Enterprise Distributed Database Ecosystem」下寫到：Building the standards and ecosystem on top of heterogeneous databases, empowering enterprise data architecture transformation。這說明的是專案邊界，不是已完成的生產驗證。

從 README 的「OVERVIEW」與相關條目，可以先判斷它是否處理你的實際問題：Enhance: As a database computing enhancement engine, transparently providing enterprise-grade capabilities including distributed computing (data sharding, readwrite-splitting, SQL federation), data security (encryption, masking, audit),。若需求不同，不應只因專案熱度就採用。本文保留原始專案名、命令與元件名，方便回到一手來源核對。 README 另外列出一項可核對的資訊：Connect: Building database upper-layer standards, quickly connecting applications with multi-modal heterogeneous databases through flexible adaptation of database protocols, SQL dialects, and storage formats, providing unified data access。這類原文條目可用來設計試跑步驟，但不能取代實際環境測試。

README 將運作方式分散在「OVERVIEW」等段落。可確認的線索包括：Database Plus Core Concept: By building a standardized and scalable enhancement layer above databases, it makes heterogeneous databases as simple to use as a single database, providing unified governance capabilities and distributed。本文不把未寫出的架構、效能或安全邊界補成結論；真正的執行鏈仍要配合目錄、設定檔與版本標籤檢查。

第一次安裝應從 README 指出的入口開始。目前可核對的命令是： README 没有给出可直接复制的安装命令。 如果倉庫沒有命令，本文不會自行編造步驟，而是建議先閱讀「OVERVIEW」，確認系統依賴、預設埠與首次初始化。

日常使用取決於專案文件。README 的「OVERVIEW」段落提到：Connect, Enhance, and Pluggable are the three core pillars of Apache ShardingSphere:。設定檔、環境變數、權限與資料目錄只在來源明確時才會記錄；沒有寫出的預設值，應在測試環境驗證並保留回滾副本。 同一部分也提到：Pluggable: Adopting a micro-kernel + 3-layer pluggable architecture to achieve complete decoupling of kernel, functional components, and ecosystem integration.。
