The article discusses the development of a highly available spatial data demo using CockroachDB v20.2. This single-page web app showcases a tourist on a map with nearby amenities, such as pubs and cafes, updated in real-time as the user navigates the map. The demo utilizes Leaflet, Python, Flask, Mapbox, CockroachDB K8s operator, and data from OpenStreetMap. The author emphasizes the importance of highly available spatial data to avoid situations where GPS applications fail, leaving users stranded. A video and GitHub repository are provided for further exploration of this demo.
