- `GET /metrics`: Expose real-time metrics (e.g., tickets sold, available tickets per event) in a format compatible with Prometheus.
- **Atomic Ticket Purchase:** Implement the purchase logic using a Redis Lua script to atomically verify and pop a ticket from the ticket pool. This ensures no duplicate ticket sales even under massive concurrent access.
- **Fallback Mechanism:** If Redis is unavailable or fails during a purchase operation, gracefully fallback to an in-memory store (with appropriate warnings and logs), ensuring the system remains responsive (for demonstration purposes only, as in-memory stores are not persistent).
-- **Performance and Load Testing:** The service must be designed to handle tens of thousands of requests and be tested under a simulated load of at least 2000 concurrent connections. You should include logging of key performance metrics and purchase statistics.
+- **Performance and Load Testing:** The service must be designed to handle tens of thousands of requests and be tested under a simulated load of at least 5000 concurrent connections. You should include logging of key performance metrics and purchase statistics.
- **Design Documentation:** Provide a detailed design document (`design.md`) that explains your architectural decisions, how you ensure scalability, measures to handle potential bottlenecks, and details on your fallback strategy.
- **Dockerization:** Extend the docker-compose setup to include not only Redis but also (optionally) a Prometheus container to scrape and monitor the metrics from your service.
- **PDF Ticket Generation:** For every successful ticket purchase, a PDF receipt must be generated. You are free to choose any open-source PDF generation package of your choice (e.g., pdfkit, jsPDF, etc.) to implement this functionality. Ensure that PDF generation is integrated into the purchase flow without significant performance degradation.

3. **Atomic Operations with Lua:** Replace simple atomic operations (like LPOP) with a Redis Lua script that handles the ticket purchase process atomically.
4. **Fallback to In-Memory Store:** Implement a fallback mechanism that activates if Redis operations fail, ensuring continued functionality with clear logging that this is a non-persistent backup.
5. **Metrics Endpoint:** Provide a `/metrics` endpoint that returns JSON data with real-time statistics (tickets sold, tickets remaining per event, errors, etc.).
