Connection-Agnostic Presence Tracking for Stateless Distributed Back Ends
The author identified challenges in tracking device online presence across distributed processes, noting that reconnections should not be treated as offline events. They highlighted scaling concerns when connections migrate between processes. To address these issues, a paper outlining a connection-agnostic presence tracking approach was released on GitHub.
- ▪The problem involves maintaining accurate online presence for devices across multiple processes without marking reconnections as offline and then online again.
- ▪Scaling difficulties arise when a connection moves from one process to another, affecting system performance.
- ▪The author authored a paper proposing a connection-agnostic presence tracking solution for stateless distributed back ends.
- ▪The paper, version 1.3.0, is available as a PDF download on GitHub.
- ▪The work aims to improve scalability and reliability in distributed system architectures.

Opening excerpt (first ~120 words) tap to expand
i was facing problem of tracking online presence of devices across processes. reconnection shouldn't mark them as offline and then online again. and other scaling issues, like when connection moves from one process or another.so i wrote a simple paper with my ideas. i hope you guys will find it interesting.https://github.com/sku0x20/connection-agnostic-presence-tracking/releases/download/v1.3.0/main.pdf
