分析SQLite在现代应用架构中重新崛起的原因，以及Turso、Litestream等新兴工具生态。
Analyzing SQLite's resurgence in modern application architecture and the emerging tool ecosystem including Turso and Litestream.
SQLite的优势重新被发现SQLite不需要独立的数据库服务器——它是一个嵌入在应用进程中的数据库引擎。随着边缘计算和Serverless的兴起，"数据库即文件"的简洁性重新成为优势。单文件部署、零配置、读性能极高（本地磁盘访问，无网络延迟）、支持事务、存储效率比MySQL高30%。新兴生态Turso（libSQL）：SQLite的分布式版本，支持多副本复制和边缘部署。Litestream：将SQLite变更实时流式备份到S3。LiteFS：FUSE文件系统层面的SQLite复制，适合Fly.io等边缘部署平台。D1（Cloudflare）：基于SQLite的Serverless数据库服务。何时不用SQLite高并发写入场景（SQLite使用文件锁，写入串行化）；需要多进程并发写入；数据量超过TB级；需要复杂的权限控制和用户管理。这些场景仍然需要PostgreSQL或MySQL。
SQLite's Advantages RediscoveredSQLite requires no separate database server — it's a database engine embedded in the application process. With the rise of edge computing and Serverless, "database as file" simplicity has regained its advantage. Single-file deployment, zero configuration, extremely high read performance (local disk, no network latency), transaction support, and 30% better storage efficiency than MySQL.Emerging EcosystemTurso (libSQL): Distributed SQLite with multi-replica replication and edge deployment. Litestream: Real-time streaming backup of SQLite changes to S3. LiteFS: FUSE filesystem-level SQLite replication for edge platforms like Fly.io. D1 (Cloudflare): SQLite-based Serverless database service.When Not to Use SQLiteHigh-concurrency write scenarios (SQLite uses file locks, serializing writes); multi-process concurrent writes needed; data exceeding TB scale; complex permission controls required. These scenarios still need PostgreSQL or MySQL.
