C++ Declarative API – Implementation Overview Within the XRootD Framework

brief description of the XRootD architecture and its purpose within the Worldwide Large Hadron Collider Computing Grid (WLCG), alongside an overview of the server-and client- sides of the XRootD framework are discussed in the present work. The client-side of XRootD has a relatively new feature called Declarative API. Its main objective is to provide the user with an asynchronous interface that is more in line with the modern C++ paradigm. A discussion on the development process for the new API is made, together with a case study that involves the implementation of an Erasure Coding plug-in for the client.
