Report #96315

[architecture] SQLite versus PostgreSQL single server database choice low traffic

Use SQLite in WAL \(Write-Ahead Logging\) mode for read-heavy, low-concurrency workloads \(<1k TPS\) on a single server with zero external dependencies; switch to Postgres when you need network clients, row-level locking, concurrent writes, or fine-grained access control

Journey Context:
Developers over-provision Postgres for simple apps, adding operational complexity \(connection pooling, vacuuming, backups\). SQLite in WAL mode allows concurrent reads during writes and is faster for local disk workloads. However, SQLite's file-level locking serializes writes, making it unsuitable for high-concurrency web backends. The 'serverless' nature eliminates network latency.
