Challenges Faced and Solutions
Problem:
During the development of the AI-powered course search feature, we encountered significant latency issues when generating OpenAI embeddings for course content in real-time. Each search query required embedding generation and vector similarity calculations across the entire course catalog, resulting in response times of 3-5 seconds and high API costs from repeated OpenAI calls.
Solution:
We implemented a pre-computed embedding strategy with efficient vector search to optimize performance:
Batch Embedding Generation: Created a background job that pre-generates embeddings for all course content during data seeding and updates, storing them directly in MongoDB documents.
Vector Similarity Caching: Implemented MongoDB vector search using indexed embeddings, reducing search time from 3-5 seconds to under 200ms.
Smart Caching Layer: Added Redis caching for frequently searched terms and popular course recommendations, further reducing OpenAI API calls by 80%.
Incremental Updates: Built a system to only regenerate embeddings when course content is modified, maintaining data freshness while minimizing API costs.
Problem:
We faced duplicate enrollment issues where users could purchase the same course multiple times due to race conditions between Stripe webhook processing and enrollment validation. Additionally, failed payment webhooks occasionally left users with successful Stripe charges but no course access, creating customer service issues.
Solution:
We implemented idempotent enrollment processing with robust webhook handling:
Database Constraints: Added unique compound indexes on userId and courseId in the cohorts collection to prevent duplicate enrollments at the database level.
Stripe Webhook Idempotency: Implemented webhook event tracking using Stripe's event.id to ensure each payment event is processed exactly once, preventing duplicate enrollments.
Transaction Rollback System: Used MongoDB transactions to ensure atomicity - if enrollment creation fails after successful payment, the system triggers a Stripe refund automatically.
Payment Verification Middleware: Added enrollment verification before course access, cross-referencing both successful Stripe payments and database enrollment records.
Problem:
When implementing the dashboard with Next.js App Router, we encountered hydration mismatches between server and client components, especially with authentication state from Clerk and dynamic course progress data. The dashboard would flash loading states or show incorrect user data, creating a poor user experience.
Solution:
We restructured the application architecture using proper SSR patterns and state management:
Server Component Optimization: Moved authentication checks and initial data fetching to server components, ensuring consistent data on both server and client.
Suspense Boundaries: Implemented React Suspense with proper loading states for dynamic content, eliminating hydration mismatches while maintaining smooth UX.
Progressive Enhancement: Used client components only for interactive features (animations, form submissions), while keeping data display in server components.
Authentication Middleware: Created custom middleware that handles authentication state before page rendering, ensuring consistent user data across all routes.
Problem:
As the course catalog grew, MongoDB query performance degraded significantly when filtering courses by multiple criteria (skill level, price range, duration, ratings). Complex aggregation queries for the course listing page were taking 2-3 seconds to load, especially when combined with user-specific enrollment status checks.
Solution:
We optimized database performance through strategic indexing and query optimization:
Compound Indexes: Created compound indexes on frequently queried combinations (level, price, rating) and added text indexes for course name and description searches.
Aggregation Pipeline Optimization: Restructured aggregation queries to use $match stages early in the pipeline, reducing the dataset size before expensive operations.
Enrollment Status Caching: Implemented user-specific caching for enrollment status using Redis, eliminating the need for complex joins on every page load.
Pagination with Cursors: Replaced offset-based pagination with cursor-based pagination using MongoDB's _id field, improving performance for deep pagination scenarios.
