[Grafana] What is the best timeseries databases to store sizeable blobs and that can be graphed on Grafana

So in terms of problematic exemplars there’s a couple of things to be said:

  1. Metrics (as in some series of (ts, value) pairs) are not de-aggregatable. This is a design limitation, since it would be prohibitively expensive to store them that way.
  2. The answer is usually sampling - Prometheus has exemplars, which have some support in Grafana 7.4.
  3. In terms of links, Grafana has support for data links (https://grafana.com/docs/grafana/latest/linking/data-links/).
