[architecture] When to choose SQLite over client-server databases for production workloads

Deploy SQLite in WAL \(Write-Ahead Logging\) mode for single-node, read-heavy applications with co-located app and database; migrate to Postgres only when you require network access from multiple clients, high write concurrency \(>1000 TPS sustained\), or row-level security features.

Journey Context:
The conventional wisdom that 'SQLite is only for development' ignores its ACID compliance, zero-configuration operational model, and performance characteristics. With WAL mode enabled, SQLite allows concurrent readers and a single writer, achieving 60,000\+ transactions per second on local SSDs—sufficient for most web applications. The operational simplicity \(single file backup, no socket overhead, no connection pooling complexity\) dramatically reduces infrastructure cost and latency for edge computing, embedded systems, and containerized single-replica apps. The failure mode is write concurrency: multiple processes writing simultaneously create lock contention. Additionally, SQLite performs poorly on network filesystems \(NFS, EFS\), so it cannot be used with shared storage across multiple container replicas. The decision boundary is topology \(single-node vs. distributed\), not data size \(SQLite supports TBs\).
