Iago's design met our immediate needs in terms of replicating our production traffic cheaply (hey its open source) at high scale. I have to give a quick kudos to the Iago design team and contributors as it was able to help drive load problems out of parts of our system where other load tools had been running quite fine for months.
However, my team including myself, have minimal experience with Scalable Language. While we catch up our skill sets, we wrote a very quick module in pure java for restful API testing. Hopefully this may help others as they get started learning the Iago framework but may lack experience in Scalable Language.
