🔍 What’s Covered:
✅ How to design a real-time collaborative text editor like Google Docs
✅ Using WebSocket for live bi-directional communication between users
✅ Implementing Operational Transformation (OT) for concurrent edit conflict resolution
✅ Maintaining the canonical document in Redis for low-latency OT operations
✅ Real-time cursor position tracking and user presence updates
✅ Streaming document changes to Kafka for durability and async processing
✅ Periodically saving document snapshots to S3 and managing version history
✅ Rehydrating document state when Redis TTL expires using snapshot + Kafka
✅ Handling edge cases: version mismatch, user joins mid-session, Redis recovery
✅ Comparing CRDT vs OT, and why OT suits this use case better
