*Function type: Type conversion

Flux does not support duration column types. The example below converts an integer to a duration and stores the value as a string.

  1. from(bucket: "sensor-data")
  2. |> range(start: -1m)
  3. |> filter(fn:(r) => r._measurement == "system" )
  4. |> map(fn:(r) => ({ r with uptime: string(v: duration(v: r.uptime)) }))
