Durable Objects (DO) is a novel approach to cloud computing that allows application code to run directly on the machine where data is stored, eliminating network latency and synchronization issues. SQLite-in-DO takes this concept further by supporting full SQL query interface with tables and indexes through SQLite integration. This results in faster reads and writes, as well as improved reliability and consistency. SQLite-backed DOs are currently available in beta for developers to experiment with and provide feedback.
