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.
You can self-host an API serving open data (I also develop https://github.com/ajnisbet/opentopodata/ which helps you do this) but elevation data comes in different formats and quality levels which are non-trivial to merge without artefacts, and the datasets are too large for a typical cloud workflow.
