SQLite 自己搞了一套使用雲端空間為儲存空間的技術：「Cloud Backed SQLite」，對應的 Hacker News 討論可以看「Cloud Backed SQLite (sqlite.org)」這邊。
他說目前支援 Azure Blob Storage 與 Google Cloud Storage，這點比較有趣，沒有提到 Amazon S3：
The system currently supports Azure Blob Storage and Google Cloud Storage. It also features an API that may be used to implement support to other cloud storage systems.
跟之前的 sql.js 專案不太一樣，sql.js 的作法是用 HTTP range 存取現有的 SQLite 資料庫檔案，而這次的這個專案則是改變底層架構，去配合雲端環境的特點。
雲端的 storage 因為每個 access 都會有很高的 latency (相比於本地的空間)，所以要避免太多 random access，儘量以 sequential access 為主，這個特性像是以前在處理傳統磁頭硬碟時的技巧。
另外一個特點是雲端空間有多檔案的概念，所以也可以利用這個方式設計資料結構。
還蠻有趣的計畫，而且是官方搞的…
