SQLite as Your Server Database

SQLite on the server as a PostgreSQL replacement for indie and startup workloads — covering Litestream for continuous S3 replication, WAL mode tuning on ext4/btrfs, single-writer concurrency semantics with Ktor and Spring Boot connection handling, and the specific throughput and concurrency boundaries where SQLite stops being viable. Includes realistic benchmarks against PostgreSQL for typical SaaS read/write patterns and the migration escape hatch when you outgrow it.
