All Implemented Interfaces:

NamedWriteable, Writeable, Resolvable, PromqlPlan

public final class HistogramQuantile
extends PromqlFunctionCall

Dedicated logical node for PromQL histogram_quantile() over classic histograms. The function consumes the cumulative bucket counts identified by the le label and produces the same label set as its child except for le.

info

protected NodeInfo<PromqlFunctionCall> info()

Description copied from class: Node

Normally, you want to use one of the static create methods to implement this.

For QueryPlans, it is very important that the properties contain all of the expressions and references relevant to this node, and that all the properties are used in the provided constructor; otherwise query plan transformations like QueryPlan#transformExpressionsOnly(Function) will not have an effect.

Specified by:

info in class Node<LogicalPlan>

replaceChild

public HistogramQuantile replaceChild(LogicalPlan newChild)

Specified by:

replaceChild in class UnaryPlan

output

public List<Attribute> output()

Description copied from class: QueryPlan

The ordered list of attributes (i.e. columns) this plan produces when executed. Must be called only on resolved plans, otherwise may throw an exception or return wrong results.

Specified by:

output in interface PromqlPlan

Overrides:

output in class PromqlFunctionCall

functionType

public FunctionType functionType()

Specified by:

functionType in class PromqlFunctionCall
