Solo dev slashes latency 90x by moving services from Postgres to SQLite

A solo developer has successfully migrated five internal services from managed PostgreSQL databases, such as Neon and Supabase, to SQLite. This transition significantly reduced latency, with query times dropping from an average of 38ms to under 1ms in one instance, and also lowered operational costs and complexity. The developer credits advancements in SQLite's WAL mode, the availability of Litestream for reliable backups to S3, and the integration of `sqlite-vec` for handling embeddings without needing a separate vector database.
