Report #51245

[architecture] Postgres connection pool exhaustion and latency overhead for simple read-heavy app

Use SQLite in WAL \(Write-Ahead Logging\) mode for single-node deployments with <100K TPS, avoiding network roundtrips and connection limits. Enable WAL with \`PRAGMA journal\_mode=WAL;\`.

Journey Context:
Postgres requires TCP/IP overhead, process-per-connection model \(or pooler complexity\), and operational maintenance for small apps. SQLite runs in-process with zero IPC latency. WAL mode allows concurrent readers and a single writer, dramatically improving concurrency over DELETE journal mode. Litestream enables streaming backups, removing the last operational blocker for production SQLite use.
