⚡ Bolt: Parallelize independent sequential database queries

[fatelessdev]

💡 What: Replaced sequential database queries with Promise.all() to run them concurrently in app/api/products/route.ts and lib/actions/admin.ts.
🎯 Why: Awaiting independent sequential database queries creates an unnecessary waterfall of requests, increasing total load time and latency.
📊 Impact: Expected to significantly reduce latency when fetching paginated product queries and dashboard statistics.
🔬 Measurement: Can be verified by observing the total time taken to fetch products and dashboard stats, or by timing the execution duration of these specific functions.

📝 Walkthrough

Walkthrough

The PR replaces sequential database queries with concurrent execution using Promise.all() in two key files. In the products API route, it parallelizes the paginated product fetch and total count query. In the admin actions, it parallelizes four independent dashboard statistics queries.

💡 Suggestions & Improvements

• Performance: The parallelization changes are excellent. Consider applying this pattern to other independent queries throughout the codebase (e.g., getOrderById which fetches order and items sequentially).
• Maintainability: The .jules/bolt.md documentation is a great practice for capturing learnings. Consider adding similar notes for other optimization patterns.
• Best Practices: The code follows Drizzle ORM patterns correctly. Ensure error handling remains robust when queries run in parallel (current try/catch blocks handle this appropriately).
