kbarbel640-del Query Optimizer
Slow queries killing your app? Paste your SQL or Prisma code and get optimization suggestions. Index recommendations, query rewrites, N+1 detection. The stuff that takes hours to figure out manually.
One command. Zero config. Just works.
Quick Start
npx ai-query-optimize "SELECT * FROM users WHERE email LIKE '%@gmail.com'"
What It Does
- Analyzes SQL and Prisma queries for performance issues
- Suggests missing indexes with CREATE INDEX statements
- Rewrites queries to avoid common antipatterns
- Detects N+1 problems in ORM code
- Explains why changes improve performance
Usage Examples
# Optimize a SQL query
npx ai-query-optimize "SELECT * FROM orders WHERE created_at > NOW() - INTERVAL '30 days'"
# Analyze a Prisma query file
npx ai-query-optimize queries.ts
# Check for N+1 issues
npx ai-query-optimize src/api/users.ts --check-n-plus-one
# Get index recommendations
npx ai-query-optimize schema.sql --suggest-indexes
Best Practices
- Include your schema - Context about tables and existing indexes helps a lot
- Measure before and after - EXPLAIN ANALYZE doesn't lie
- Test with real data - Optimizations that work on 100 rows might fail on 1M
- Don't optimize prematurely - Fix actual slow queries, not theoretical ones
When to Use This
- Database queries are showing up in your APM as slow
- Users are complaining about loading times
- You inherited a codebase with questionable query patterns
- Learning SQL optimization and want to understand the patterns
