High-Performance SQLite Microservices in Go

SQLite is often overlooked as a production database, but when combined with WAL journal mode (PRAGMA journal_mode = WAL), synchronous = NORMAL, and Go's standard net/http package, it becomes an unbeatable stack for low-latency web services.

Key Optimizations: - WAL Mode: Writes don't block reads, enabling concurrent read transactions. - Busy Timeout: Prevents SQLITE_BUSY errors under bursty traffic. - Single Connection Slot: Setting SetMaxOpenConns(1) avoids lock contention in Go's connection pool. - Embedded Binaries: Combining //go:embed with SQLite creates self-contained deployments.
