Clj-headlights is a toolset for Apache Beam to use Clojure code and construct pipelines.
It is not intended as a full replacement for the Beam Java SDK, nor a complete abstraction layer. As a clj-headlights user, you are expected to know the Beam programming model. Its intent is to make Clojure play nice enough with the official SDK and provide helpers for tedious operations.
Latest stable version

Versioned based on the major and minor versions of the Beam API, plus a patch version for our version.
lein with-profile uberjar install
You'll need to generate a deploy key on clojars and save it somewhere safe. We have one in CloudAI gopass currently.
After committing and tagging with the version in project.clj being a release version and not a snapshot, run the following:
lein with-profile uberjar deploy clojars
