We are excited to announce the open-source release of Apodini, one of our internal libraries. Here at Sonian, we are committed to quality software and to contributing to the projects that have helped us so much, and Apodini is another way of us saying, “Thanks!”

What is Apodini?

Apodini is a Clojure-native REST client for Rackspace CloudFiles and OpenStack Swift. Written entirely in Clojure from the ground up, it provides a comfortable functional interface for Clojure developers working with the CloudFiles family of object stores. In case you were wondering, the name ‘Apodini’ comes from the taxonomy of swifts, one of the fastest flying birds in the world.

One of the key components to Sonian’s Information Discovery Cloud is having easy, consistent and well-understood tools with which we can innovate over technologies like cloud-based object stores. Sonian is a user of, and a contributor to, the OpenStack project. We have been “pioneering” the use of cloud object stores for over six years, and understand the nuances between the various offerings. We created Apodini to be a library that is the right fit for us. Now we hope it can be the right fit for your project, too.

Why did we build Apodini?

With Apodini, we’ve been able to more easily understand the code we need to make the best use of our Swift and CloudFiles object stores. We’ve also been able to make quick and easy changes, and tailor it to suit our evolving needs, such as supporting multiple authentication methods. Apodini also provides easy-to-use functional abstractions; for example, lazy sequences over object listings that completely takes pagination out of the list of things developers need to worry about.

Where is Apodini?

It’s available on github! Go to and check it out. It’s also available for use directly from your Clojure project’s configuration, just add it to your project.clj and you’re all set.

Apodini is made available under the Apache 2.0 license, which you can read here:
