Report #78987

[architecture] When does SQLite outperform Postgres/MySQL for production web services?

Use SQLite with WAL \(Write-Ahead Logging\) mode enabled for low-to-moderate write throughput \(<1000 TPS\), single-node deployments where application and database reside on the same failure domain; avoid network hops and connection pool complexity.

Journey Context:
Common mistake is using default SQLite DELETE journaling mode which locks the entire database on writes, causing concurrency failures. WAL mode allows readers to proceed without blocking writers and vice versa. Tradeoffs: SQLite handles concurrency poorly across network filesystems \(NFS\) and lacks row-level security/replication features of Postgres. Right call when: single-tenant SaaS with many small databases \(one per customer\), embedded devices, or rapid prototyping where operational simplicity beats raw throughput.
