SQLite in Production: Lessons Learned

# SQLite in Production: Lessons Learned

SQLite can power production apps. Here's what I learned.

## When SQLite Works

- **Read-heavy** apps (blogs, docs)
- **Single server** deployments
- **Development/Testing**
- **Embedded** applications

## When to Avoid

- **High write concurrency**
- **Multi-server** deployments
- **Large datasets** (> 100GB)

## Optimization Tips

### WAL Mode

```sql
PRAGMA journal_mode = WAL;
```

Better concurrency!

### Memory Mapping

```sql
PRAGMA mmap_size = 268435456;
```

### Proper Indexing

Index everything you query.

## Backup Strategy

```bash
sqlite3 database.db ".backup 'backup.db'"
```

## Monitoring

Track:

- Database size
- Query times
- Lock waits

## Conclusion

SQLite is viable for production when used appropriately. Don't dismiss it!
