[architecture] When to choose SQLite over Postgres for production web services

Enable SQLite with WAL \(Write-Ahead Logging\) mode for read-heavy workloads \(<1000 writes/sec\), single-node deployments, and zero-ops requirements; avoid for multi-writer concurrency or network filesystems

Journey Context:
Teams default to Postgres for 'serious' applications, adding Docker, connection pools, and backup complexity. SQLite with WAL supports high read concurrency \(thousands of readers\) and is significantly faster for reads. WAL mode allows readers to not block writers. Common mistakes: using SQLite on NFS \(network filesystem\) which breaks file locking, or using default DELETE journal mode which has worse concurrency. SQLite is wrong choice if you need multiple processes writing heavily or row-level locking.
