Round 2 - LLD/ Design Round
📌 LLD Question: Feature Toggle System
Design a Feature Toggle Service for an application (e.g., streaming platform like Netflix) that allows enabling or disabling features dynamically.
🧩 Requirements
The system should allow:
- Add, enable, disable, and remove features
Each feature may have rules:
- Subscription-based (e.g., Premium)
- Region-based (e.g., IN)
- If no rule → feature available to all users
- Check if a feature is enabled for a given user
