Ephemeral Channels for Real-Time Document Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Real-time collaboration systems in group-based communication face bottlenecks and scalability issues as the number of users increases, leading to latency and inefficiencies in managing real-time updates in document collaboration sessions.
Innovation Solution
Implementing a system with multiple servers to handle real-time updates, where ephemeral channels are created for document collaboration sessions, users are subscribed and unsubscribed based on connection status, and real-time events are transmitted to subscribed users, along with mechanisms for handling reconnects and permission changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single server handles all real-time updates for document collaboration sessions, then the system is simpler to manage, but bottlenecks and latency increase as the number of users grows
Solution Approach 1:
The system segments the real-time update handling by creating separate ephemeral channels for different document collaboration sessions. Each channel operates independently, allowing parallel processing of updates across multiple sessions. This segmentation prevents a single server from becoming a bottleneck while maintaining manageable system complexity through modular channel-based architecture.
2Productivity
If multiple servers are implemented to handle real-time updates, then scalability and performance improve, but system complexity increases
Solution Approach 1:
The system introduces an intermediary layer of ephemeral channels that manage the complexity of multiple servers. These channels act as mediators between users and the underlying server infrastructure, abstracting away the complexity of distributed server management while enabling scalable real-time update handling across multiple servers.
3Speed
If users remain subscribed to channels after disconnecting, then reconnection is faster, but resource consumption and latency increase
Solution Approach 1:
The system implements dynamic subscription management where user subscriptions to ephemeral channels are automatically adjusted based on connection status. When users disconnect, their subscriptions are suspended rather than terminated, allowing for rapid reconnection while preventing continuous resource consumption during disconnection periods. This dynamic approach balances reconnection speed with resource efficiency.

AI summary
Media, methods, and systems are provided for real-time updates of collaborative documents in a group-based communication system. Collaborative documents may allow for multiple users to simultaneously modify and edit a document. When a collaborative document is created, a server may create an ephemeral channel and an identifier for the collaborative document. As users connect to the collaborative document, the users may be assigned a temporary subscription to the collaborative document. Real-time events, such as indications that a user is typing, indications that a user is connected in the collaborative document, and changes to the collaborative document may be published to the user via the temporary subscription. When the user disconnects from the document, the real-time events may no longer be communicated.
