# Query Optimization Report

**Generated:** $(date)
**Database:** $DB_TYPE
**ORM:** $ORM_TYPE
**Project:** $(basename $(pwd))

---

## Analysis Summary

### N+1 Queries
- Instances found: $N_PLUS_ONE_FOUND
- Impact: HIGH - Can cause exponential query growth
- Fix: Use eager loading (include, select_related, prefetch_related)

### Missing Indexes
- Potential issues: $MISSING_INDEXES
- Impact: MEDIUM-HIGH - Causes full table scans
- Fix: Add indexes to frequently queried columns

---

## Critical Optimizations

### 1. Fix N+1 Queries (Priority: CRITICAL)

**Problem:** Loading related data in loops causes N+1 queries.

**Examples:**

#### Prisma
\`\`\`typescript
// ❌ BAD: N+1 query
const users = await prisma.user.findMany();
for (const user of users) {
    const posts = await prisma.post.findMany({ where: { userId: user.id } });
}

// ✅ GOOD: Single query with include
const users = await prisma.user.findMany({
    include: { posts: true }
});
\`\`\`

#### Django ORM
\`\`\`python
# ❌ BAD: N+1 query
users = User.objects.all()
for user in users:
    posts = user.post_set.all()  # Separate query per user

# ✅ GOOD: Use prefetch_related
users = User.objects.all().prefetch_related('post_set')
\`\`\`

#### TypeORM
\`\`\`typescript
// ❌ BAD: N+1 query
const users = await userRepository.find();
for (const user of users) {
    user.posts = await postRepository.find({ where: { userId: user.id } });
}

// ✅ GOOD: Use relations
const users = await userRepository.find({
    relations: ['posts']
});
\`\`\`

### 2. Add Missing Indexes (Priority: HIGH)

**Problem:** Queries without indexes cause full table scans.

**Index WHERE/JOIN columns:**

#### PostgreSQL/MySQL
\`\`\`sql
-- Add index on email for login queries
CREATE INDEX idx_users_email ON users(email);

-- Add index on foreign key
CREATE INDEX idx_posts_user_id ON posts(user_id);

-- Composite index for multi-column queries
CREATE INDEX idx_posts_user_status ON posts(user_id, status);

-- Partial index for filtered queries
CREATE INDEX idx_active_users ON users(id) WHERE status = 'active';
\`\`\`

#### MongoDB
\`\`\`javascript
// Single field index
db.users.createIndex({ email: 1 });

// Compound index
db.posts.createIndex({ userId: 1, createdAt: -1 });

// Text index for search
db.articles.createIndex({ title: "text", content: "text" });
\`\`\`

### 3. Optimize Query Patterns (Priority: MEDIUM)

**Use projection to select only needed fields:**

\`\`\`typescript
// ❌ BAD: Select all columns
const users = await prisma.user.findMany();

// ✅ GOOD: Select only needed fields
const users = await prisma.user.findMany({
    select: { id: true, email: true, name: true }
});
\`\`\`

**Use pagination for large datasets:**

\`\`\`typescript
// ✅ GOOD: Paginate results
const users = await prisma.user.findMany({
    skip: (page - 1) * pageSize,
    take: pageSize
});
\`\`\`

**Use EXISTS instead of COUNT for existence checks:**

\`\`\`sql
-- ❌ BAD: Count all rows
SELECT COUNT(*) FROM posts WHERE user_id = 123;

-- ✅ GOOD: Check existence
SELECT EXISTS(SELECT 1 FROM posts WHERE user_id = 123 LIMIT 1);
\`\`\`

## Database-Specific Optimizations

### PostgreSQL
- Use \`EXPLAIN (ANALYZE, BUFFERS)\` to analyze queries
- Enable \`pg_stat_statements\` for slow query logging
- Use \`VACUUM ANALYZE\` regularly
- Consider \`BRIN\` indexes for time-series data
- Use \`CONCURRENTLY\` when creating indexes on large tables

### MySQL
- Use \`EXPLAIN\` to analyze queries
- Enable slow query log
- Use \`ANALYZE TABLE\` to update statistics
- Consider \`FULLTEXT\` indexes for text search
- Optimize \`JOIN\` buffer size

### MongoDB
- Use \`.explain("executionStats")\` to analyze queries
- Enable profiler: \`db.setProfilingLevel(1, { slowms: 100 })\`
- Use covered queries (query + projection use same index)
- Shard large collections
- Use aggregation pipeline efficiently

## Query Performance Checklist

- [ ] Identify and fix all N+1 queries
- [ ] Add indexes to frequently queried columns
- [ ] Add indexes to foreign key columns
- [ ] Use composite indexes for multi-column queries
- [ ] Analyze slow queries with EXPLAIN
- [ ] Use connection pooling
- [ ] Implement query result caching
- [ ] Use pagination for large result sets
- [ ] Select only needed columns (projection)
- [ ] Optimize JOIN order in complex queries
- [ ] Review and remove unused indexes
- [ ] Monitor query performance in production

---

## Monitoring & Maintenance

### Enable Query Logging

**PostgreSQL:**
\`\`\`sql
-- In postgresql.conf
log_min_duration_statement = 100  # Log queries > 100ms
\`\`\`

**MySQL:**
\`\`\`sql
SET GLOBAL slow_query_log = 'ON';
SET GLOBAL long_query_time = 0.1;  # 100ms
\`\`\`

**MongoDB:**
\`\`\`javascript
db.setProfilingLevel(1, { slowms: 100 });
\`\`\`

### Regular Maintenance

- Run VACUUM/ANALYZE (PostgreSQL)
- Update table statistics
- Review and optimize slow queries
- Monitor index usage
- Check for table bloat
- Review query patterns

## Next Steps

1. **Fix N+1 queries** (Critical)
   - Review flagged locations
   - Add eager loading
   - Test performance improvement

2. **Add missing indexes** (High Priority)
   - Create migration for indexes
   - Test on staging first
   - Monitor production impact

3. **Analyze slow queries** (Medium Priority)
   - Run query plan analysis scripts
   - Use EXPLAIN on slow queries
   - Optimize based on results

4. **Set up monitoring** (Ongoing)
   - Enable slow query logging
   - Monitor query performance
   - Set up alerts for slow queries
