Report #97773

[architecture] SQLite or Postgres for a new service?

Start with SQLite when the app runs on one machine, has low-to-moderate concurrency, and values zero ops overhead. Switch to Postgres when you need concurrent writers, network clients, replication, row-level security, or stored procedures.

Journey Context:
Developers default to Postgres out of habit, but SQLite is often faster for single-node workloads because it avoids IPC and the query planner is simpler. The real limit is write concurrency: SQLite handles one writer at a time. If your app has multiple servers or needs fine-grained access control, Postgres is worth the operational cost.
