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.
If you want to persist some form of context between requests you can store it in session data via a cookie that can be pulled/leveraged in the second handler, ex: https://github.com/gorilla/sessions. If you try to implement it yourself consider security aspects like that a user could modify if unsigned, etc. You can also store data server side and just issue a token in a cookie corresponding to a server side session. Hope that helps.
