Figma's next-generation data caching platform

Figma rearchitected their storage systems to support scalability, including horizontally sharding their Postgres stack and building FigCache, a stateless proxy service for Redis. FigCache decouples connection scalability from Redis, centralizes traffic routing, enhances security, and provides end-to-end observability. The caching layer has achieved six nines of uptime since its rollout, addressing previous operational challenges and paving the way for Figma's future growth.
