We found streams to be a breakthrough feature for pub-sub type data on IoT devices. That it can both be low-latency pub-sub and a stateful, short-lived cache is quite powerful to improve performance for many queries to the types of data generated by cameras and high-frequency sensor devices. http://atomdocs.io/ http://atomdocs.io/ https://github.com/elementary-robotics/atom https://github.com/elementary-robotics/atom
