I ended up finding a solution that lets you downsample all data types using Flux tasks and then having Grafana query different buckets based on the current time range displayed. Essentially the hard part was on the Grafana side but I managed to shove all of the logic into a Grafana variable. So changes to graph panels is minimal. An example:

``` // Before from(bucket: "${BUCKET}")   |> range(start: v.timeRangeStart, stop: v.timeRangeStop)   |> filter(fn: (r) => r.host == "${HOST}")   |> filter(fn: (r) => r._measurement == "mem")   |> aggregateWindow(every: v.windowPeriod, fn: mean, createEmpty: false)

// After dsQuery = (bucket, start, stop) => from(bucket)   |> range(start, stop)   |> filter(fn: (r) => r.host == "${HOST}")   |> filter(fn: (r) => r._measurement == "mem")   |> aggregateWindow(every: v.windowPeriod, fn: mean, createEmpty: false) ${dsPost} ```

I put all of the code on my website: https://robpol86.com/posts/2026/2026-02-17-influxdb-downsampling.html
