Abstract: A vehicle data streaming service may receive requests to register plug-ins to generate synthetic vehicle attribute data streams. A plug-in service of the vehicle data streaming service may configure a given plug-in in an internal containerized environment in a fully automated manner and/or configure the plug-in in an external compute service environment. The vehicle data streaming service may configure the plug-ins to receive input streams to generate synthetic attribute output streams. The vehicle data streaming service and the plug-in service may allow the synthetic attribute output streams to be associated with synthetic vehicle attributes included, or to be included, in a curated catalog of vehicle attributes. The vehicle data streaming service furthermore allows one or more vehicle data stream destinations to subscribe to the synthetic vehicle attributes included in the catalog.
