🐇 Bunny.net Edge Storage Go Library

This is a new Library for using the Bunny.net Object Storage Service in Go. It has been heavily inspired by James Pond`s bunnystorage-go.

❓ Why another library?

I wrote this because of a open PR implementing Bunny.net as Object Storage in JuiceFS and the maintainers were a bit hesitant merging code with many homebrew dependencies. This is using just three battletested dependencies (fasthttp, uuid, logrus) and is about 200 lines of library code, excluding tests.

• The E2E test coverage is currently at about 80%
• Simple to use
• Uses valyala/fasthttp under the hood to achive much better performance than other libraries.
• Implements Undocumented Describe funtion which allows to retrieve metadata for single, non-directory files.
• Implements HTTP Range Downloads for downloading segments of objects

🦾 Getting Started

go get github.com/l0wl3vel/bunny-storage-go-sdk

import "net/url"
import "github.com/l0wl3vel/bunny-storage-go-sdk"

endpoint, err := endpoint.Parse("https://la.storage.bunnycdn.com/mystoragezone/")
if err != nil	{
    panic(err)
}
bunnyclient = bunnystorage.NewClient(endpoint, password)

content := make([]byte, 1048576)
// Fill content with data

// The last argument controls if a checksum is included in the request
err := bunnyclient.Upload("foo/bar.txt", content, true)
if err != nil 	{
	panic(err)
}

🚀 Performance

It is fast. The use-case built this library around is for a JuiceFS storage backend, which requires low latency and high throughput. Using the other Bunny.net library which uses net/http I got around 200⬇️ 400⬆️ MiB/s from Hetzner Nürnberg to the Bunny Edge PoP.

With this library after moving to fasthttp I was able to achive 1 GB/s upload and 600 Mbit/s download.

❤️ Thanks to

• James Pond for creating the original bunnystorage-go library, which allowed me to start prototyping my work on JuiceFS immediately
• Bunny.net for creating an awesome performing and attractively priced object storage solution
