⚡ Optimize N+1 Query in Brand Product Updates#400
Conversation
- Replaced sequential `prisma.product.updateMany` calls with bulk `findMany` and `updateMany` operations in `BrandService`. - Reduced complexity from $O(N)$ database queries to $O(1)$ (exactly 2 queries: one to verify existence/accessibility and one to perform the update). - Maintained detailed error reporting by identifying missing products before the update. - Added input deduplication with `Set`. - Created comprehensive unit tests in `src/test/services/brand.service.test.ts` to verify the optimization and correctness.

💡 What:
Optimized
assignProductsToBrandandremoveProductsFromBrandinBrandServiceby replacing the N+1 database query loop with a more efficient batch operation.🎯 Why:
The previous implementation performed one
updateManycall for every product ID in the provided array. This resulted in significant performance overhead when processing large batches of products (e.g., assigning hundreds of products to a brand).📊 Measured Improvement:
findMany+ 1updateMany).storeId,deletedAt, andbrandId) in the batch update as in the original sequential updates.PR created automatically by Jules for task 8658153721038947235 started by @syed-reza98
