com.influxdb.query.dsl.Flux

com.influxdb.query.dsl.functions.AbstractParametrizedFlux

com.influxdb.query.dsl.functions.SortFlux

All Implemented Interfaces:

Expression, HasImports

public final class SortFlux
extends AbstractParametrizedFlux

Sorts the results by the specified columns Default sort is ascending. See SPEC.

Options

• columns - List of columns used to sort; precedence from left to right. Default is ["value"] [array of strings]
• desc - Sort results descending. Default false [bool]

     .from("telegraf")
     .sort(new String[]{"region", "value"});

     from(bucket:"telegraf")
          |> filter(fn: (r) => r["_measurement"] == "system" AND r["_field"] == "uptime")
          |> range(start:-12h)
          |> sort(desc: true)
