Debug This Architecture
Here's the architecture for a real-time collaborative document editor (like Google Docs): **System Overview:** - Frontend: React SPA with…
This architecture has several critical flaws that would cause data loss, stale states, high latency, and scalability limits.

Adding API servers or read replicas will not fix that. Issue and failure mode Specific solution Trade-off Client-clock last-write-wins loses work.Read the full answer
