Sharding Infrastructure: The Regional Goval Project
Replit has redesigned its core infrastructure, known as Goval, to improve reliability and scalability. The company moved from a single failure domain to multiple isolated clusters, initially partitioning by user membership. This new approach, dubbed Regional Goval, uses consistent hashing for uniform cluster sizing and places each cluster within a single cloud region to minimize cross-region connections and fault scope.
