What is a YOUnite Adaptor
...
Once an adaptor is connected to the YOUnite DataHub through the YOUnite Message Bus, it is able to send and receive data and ops messages. However, to streamline an adaptor developers time, the SDK has a minimal configuration step so that developers can focus on the business logic their adaptor is being built for and not the inner workings of sending and receiving messages, parsing those messages, and so on. To facilitate this, the YOUnite Adaptor SDK makes use of annotations developers use to define the capabilities related to the data their adaptor can produce and/or consume. These capabilities loosely translate into a Pub/Sub configuration on the YOUnite DataHub. Essentially they indicate to the YOUnite DataHub the specific domain properties they are interested in receiving changes for, and which of their own domain properties they will push out to the YOUnite DataHub when a change occurs within the associated local service(s) the adaptor is implemented to work with or domain properties requested by the YOUnite DataHub. These local services could be direct database data, an FTP server, in-memory data, or a remote service with data. In fact, the dynamic nature of YOUnite domains leave the details to individual adaptor implementations to determine how they access and retrieve domain property data and any transformations they may want to apply to the data.
