[architecture] When does SQLite actually beat Postgres for a production workload?

SQLite wins when your app is a single-node service, write concurrency is low-to-moderate \(mostly reads or short write bursts\), and you value zero deploy/backup/operational overhead. It is not 'toy Postgres'; it is a zero-configuration, serverless, transactional engine that beats a network database on latency and simplicity until you need multiple writers, row-level locking, or horizontal scaling.

Journey Context:
The common mistake is defaulting to Postgres out of fear, then paying for a managed instance, connection pools, migrations tooling, and failover that a single-box app never needed. SQLite's WAL mode gives good read concurrency and acceptable write concurrency, but it is not built for many long-running writers or high-volume OLAP. The real cost of Postgres is operational, not just hardware. Choose SQLite if your service runs on one machine, your data fits on disk, and your team does not have a DBA. Choose Postgres when you need multiple write nodes, complex access control, row-level security, partitioned tables, or streaming replicas.
