[architecture] When should I choose SQLite over PostgreSQL?

Choose SQLite when: single-server or embedded application, read-heavy workload with low concurrency, need zero configuration, or data is small \(under 1GB\). Avoid SQLite when: high write concurrency \(multiple simultaneous writers\), need advanced features like user management, replication, or horizontal scaling, or data must survive a server crash without corruption risk.

Journey Context:
Common mistake: assuming SQLite is only for mobile. SQLite is excellent for local development, testing, single-node applications, and as a cache/store for small datasets. It's faster than Postgres for simple queries because no network overhead. But it has no concurrent write support \(serialized\), no built-in replication, and can corrupt under power loss without WAL mode. Postgres offers robust concurrency, full SQL, extensions, and is better for multi-user, production workloads. The tradeoff is simplicity vs scalability.
