14	## Common Problem Patterns
15
16	### N+1 Query
17
18	```typescript
19	// ❌ Bad: N+1
20	for (const user of users) {
21	const orders = await this.orderRepo.findByUserId(user.id);
22	}
23
24	// ✅ Good: Batch query
25	const userIds = users.map(u => u.id);
26	const orders = await this.orderRepo.findByUserIds(userIds);
27	```
28
29	### Await in Large Loops
30
31	```typescript
32	// ❌ Bad: Sequential execution
33	for (const item of items) {
34	await processItem(item);
35	}
36
37	// ✅ Good: Parallel execution
38	await Promise.all(items.map(item => processItem(item)));
39	```
40
41	### Unreleased Resources
42
43	```typescript
44	// ❌ Bad: Connection not released
45	const conn = await pool.getConnection();
46	const result = await conn.query(sql);
47	// Forgot conn.release()
48
49	// ✅ Good: Use try-finally
50	const conn = await pool.getConnection();
51	try {
52	return await conn.query(sql);
53	} finally {
54	conn.release();
55	}
56	```
