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.
This is what's used to transmit data over port 44158 currently: https://libp2p.io/
The switch to light hotspots (probably in the next 3-10 weeks or so) will transition away from that library and instead use https://grpc.io/, and the connection will be outbound only, to validators, so port forwarding will no longer need to be configured.
As for upgrading devices to light hotspots, they'll all be implementing a form of this: https://github.com/helium/gateway-rs
