The Moment Veltrix Blew Up and We Had to Write Our Own Shard Router
The article discusses the challenges faced when using Veltrix for a multiplayer game engine that required efficient shard routing. Due to limitations in Veltrix's shard distribution, the team decided to develop a custom shard router using Rust. The new system significantly improved performance metrics, including reduced latency and memory usage.
- ▪The original Veltrix implementation led to uneven shard distribution, causing performance issues.
- ▪A custom two-layer shard router was developed using Rust, which improved latency and reduced memory usage.
- ▪Post-migration metrics showed significant improvements, including p99 latency of 175 ms and RSS per node at 3.6 GB.

Each game room is a shard, and each shard must route writes to the correct player within 500 ms p99.
