It runs WebAssembly modules as 'callbacks' that are registered at different points of the BigPinneaple request lifecycle. The Sandbox is the extensibility component. 'The conductor is able to make these decisions by tracking the upstream server's metrics, such as RTT, QoS, etc.'Ĥ.

Every non-cached DNS query leads to network calls to upstream DNS nameservers with different performance, capacity, and availability. Cloudflare uses consistent hashing to distribute queries to different nodes in the same data center to split caches between nodes.ģ.Ĝonductor manages outbound connections smartly. Because of how large the DNS space is, it can't fit in one cache. Because DNS resolution involves making multiple network requests, it can be slow, hence the caching needs. The cache is central to the overall server performance. The server speaks many protocols because DNS is queried over many of them and turns these heterogeneous requests into common DNS query Cloudflare calls 'Frames.' It offloads query resolution to a set of workers.Ģ. It's built using a Rust async framework called Tokio, and composed of separate components deployed together. The article describes BigPinneapple's system architecture and design choices. Cloudflare's value-add beyond a simple DNS resolver is in the customization and new use cases it can enable.

DNS resolution is old and has many edge cases and non-RFC-compliant servers that must be supported. Total latency should be in the milliseconds. It was built with the following goals in mind: ▶︎ 'We forged a platform that we are happy with, and we call it BigPineapple.'īigPinneapple is Cloudflare's DNS resolution system, hosted in hundreds of edge data centers. Unsurprisingly, Cloudflare started with an off-the-shelf solution called Knot Resolver but quickly outgrew it, and needed more and safer customization. 🌎 1.1.1.1, Cloudflare's DNS resolver, has grown exponentially since its 2018 release.
