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.
For instance, for terminal input you may want to have a look at https://github.com/rothgar/awesome-tuis, where you will find many terminal user interface libraries (and other examples). I would suggest imtui and fxtui from the libraries section. You may also want to use classic ncurses, as others have suggested.
