Report #51646

[architecture] Assuming SQLite cannot handle high-traffic web workloads due to 'serverless' architecture

Enable WAL \(Write-Ahead Logging\) mode with \`PRAGMA journal\_mode=WAL\` and serve reads from immutable read replicas \(e.g., Litestream S3 copies\) to achieve 10k\+ concurrent reads with sub-10ms latency.

Journey Context:
Developers default to Postgres for 'scale' they don't have. SQLite in WAL mode allows readers to proceed without blocking writers, eliminating the classic locking bottleneck. The game-changer is separating read and write paths: use Litestream to replicate the WAL to S3/edge locations, then serve GET requests from read-only SQLite files at the edge. This beats round-trips to a central Postgres for read-heavy workloads \(CMS, blogs, dashboards\) while maintaining ACID writes at the origin.
