InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
- build a minimal web page showing a Leaflet or a MapLibre widget, connected to a backend built using a compiled language like C++ or D, itself connecting to OSM Scout Server to provide the tiles. Or to OSM Scout Server directly if it is possible.
The last option is probably the most lightweight solution, provided you probably have a browser already running on your phone. I'm not saying this out of my ass by the way, I'm building an SMS app using Svelte for the user interface and D for the backend connecting to the modem and managing the SQLite database. It's way faster than chatty.
