When the Treasure Hunt Engine Eats Itself: My First Production Outage That Taught Me the True Cost of Defaults
The article discusses a production outage experienced while using a Lua-based treasure-hunt engine. The author details the challenges faced with memory management and latency issues, leading to a decision to rewrite the engine in Rust. The transition resulted in significant performance improvements and highlighted the importance of proper memory monitoring and architectural decisions.
- ▪The Lua heap size increased dramatically, causing latency issues and a production outage.
- ▪Initial attempts to fix the problem by tuning Lua settings failed, leading to further complications.
- ▪Switching to a Rust-based engine improved performance metrics significantly, including reduced epoch duration and memory usage.
