Super Slurper is a data migration tool developed by Cloudflare that enables large-scale data transfers between cloud object storage providers and Cloudflare R2. The original architecture, built on top of Kubernetes, faced performance bottlenecks due to shared resources with other services and limited scalability. To address these issues, Cloudflare rearchitected Super Slurper using their Developer Platform, incorporating features like Cloudflare Workers, Durable Objects, and Queues. This new architecture improved transfer speeds by up to 5x, allowing for faster migrations of petabytes of data. The updated service now handles duplicate messages more effectively, ensuring each object is transferred only once. With its improvements, Super Slurper has become a crucial tool for developers to migrate their data from various cloud storage providers to R2.
