Zero-latency SQLite storage in every Durable Object
Sep 26, 2024Kenton Varda

Summary
This post introduces the integration of SQLite with Durable Objects (DOs), enabling zero-latency local storage access. It details how DOs run application code on the same thread as the data, eliminating network latency. The post explains the benefits of synchronous SQL queries for avoiding subtle bugs and introduces 'Output Gates' to ensure durability without sacrificing throughput or increasing latency. It also highlights how this architecture simplifies common patterns like N+1 query problems by allowing single, efficient queries.
