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.
I'd probably go with a more of a robust solution, like using a red5 server, https://github.com/Red5/red5-server. I'd also look at something like this for Flutter.
