Collaborative Real-time Document Editor

Design a Real-time Collaborative Document Editor

Design a scalable, real-time collaborative editing system similar to Google Docs. The system must support millions of users, provide sub-100ms latency for keystroke synchronization, and handle concurrent edits gracefully using a robust conflict resolution strategy. Focus on the core mechanics of synchronization, document versioning, and the challenges of maintaining a consistent state across distributed clients while ensuring high availability and durability.

Real-time Collaborative Document Editor

Design a system similar to Google Docs that enables multiple users to edit the same document simultaneously in real-time. The system must handle conflict resolution, maintain document history, and show user presence (who is currently online). Focus on low-latency synchronization (under 100ms) and high availability for millions of concurrent documents. Discuss the trade-offs between different consistency models and how you would scale the synchronization engine.

Collaborative Real-time Document Editor

Design a collaborative document editing system similar to Google Docs. The system must support real-time concurrent editing for multiple users, preserve document history, and handle conflict resolution seamlessly. Ensure the architecture can scale to millions of users while maintaining low latency for a smooth user experience. Discuss the trade-offs between different consistency models and how you would handle high-concurrency hotspots on a single document.
