I want to plot live time-series data while minimizing network traffic. In Grafana, when the panel reloads at a set interval, it queries the full dataset within the selected time range. However, in my case, past data doesn’t change, so I don’t need to fetch it again.
Instead, I only want to query and retrieve new data since the last update while keeping all previously loaded data displayed. I know some databases have caching features, but since my goal is to reduce network traffic, that solution doesn’t work for me.
How can I implement such a caching mechanism in Grafana?
