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.
However, checking the library I am using - AceButton - the docs prefer using a circuit that isn't a ladder as such, rather just parallel resistors, one per button.
