Over the last 5 years many NoSQL vendors have relicensed their software, and the landscape is only becoming more tumultuous with several vendors recently playing a licensing game which is akin to Musical Chairs. Developing a new NoSQL database is no small feat, and we must eventually choose some sort of license for our users. We examine what is driving the licensing changes in the wider database community, how they apply to a new entrant to the marketplace, and ultimately ask the question, are we still Open Source?
