SQLite vs Other DBsIntermediate
1Question 1 of 1
sqlWhen should you choose SQLite over client-server databases like PostgreSQL or MySQL?
Explanation & Concept
Choose SQLite for: • Embedded software, mobile apps (iOS / Android), desktop apps (Electron), and IoT devices. • Local development, unit testing, and edge computing (Cloudflare D1, Fly.io LiteFS). • Medium-traffic web apps where writes are moderate and reads dominate.
Choose PostgreSQL/MySQL for: • High concurrent write throughput distributed across multiple servers. • Complex access control, enterprise replication, or datasets exceeding multiple terabytes.
Code Example

-- Pragmas to optimize SQLite for web application workloads
PRAGMA journal_mode = WAL;
PRAGMA synchronous = NORMAL;
PRAGMA cache_size = -64000; -- 64MB RAM cache
PRAGMA busy_timeout = 5000; -- Wait 5s on lock before throwing SQLITE_BUSYHow It Works & Key Takeaways
With these pragmas configured, SQLite easily sustains thousands of reads and hundreds of writes per second on modern NVMe drives.
