Rust Rewrite, Postgres Exit: Blitz Revamps Its “League of Legends” Backend

Blitz, a startup offering personalized gaming coaching for popular titles like League of Legends, restructured its backend to improve performance, scalability, and cost-efficiency by transitioning from Postgres and Elixir to ScyllaDB and Rust. As their user base expanded, the original architecture faced challenges in handling the increasing data volume, prompting a shift to ScyllaDB for its ability to manage high write throughput and horizontal scalability, alongside a move to Rust for its memory safety and robust ecosystem. This overhaul significantly reduced infrastructure complexity and costs, replacing extensive microservices with a minimal setup that still meets performance goals, leading to a more efficient system with enhanced real-time data processing capabilities for improved user experiences.
