Package com.influxdb.query.dsl.functions

Class TimeShiftFlux

java.lang.Object

com.influxdb.query.dsl.Flux

com.influxdb.query.dsl.functions.AbstractParametrizedFlux

com.influxdb.query.dsl.functions.TimeShiftFlux

All Implemented Interfaces:

Expression, HasImports

public final class TimeShiftFlux
extends AbstractParametrizedFlux

Shift add a fixed duration to time columns. See SPEC.

Options

• duration - The amount to add to each time value [duration]
• columns - The list of all columns that should be shifted. Defaults `["_start", "_stop", "_time"]` [array of strings].

Example

 Flux flux = Flux
     .from("telegraf")
     .timeShift(10L, ChronoUnit.HOURS);

 Flux flux = Flux
     .from("telegraf")
     .timeShift(10L, ChronoUnit.HOURS, new String[]{"_time", "custom"});
