Maintainers are key to an open-source project like Delta Lake since they manage contributions and work with the developer community to further the direction of the project. They are vital to the success of the open-source project and are committed to improving it. In this blog post, we will be highlighting a lead maintainer at Delta Lake,  Florian Valeye.
