Enum Class PromqlFunctionRegistry.CounterSupport

java.lang.Object

java.lang.Enum<PromqlFunctionRegistry.CounterSupport>

org.elasticsearch.xpack.esql.expression.promql.function.PromqlFunctionRegistry.CounterSupport

All Implemented Interfaces:

Serializable, Comparable<PromqlFunctionRegistry.CounterSupport>, Constable

Enclosing class:

PromqlFunctionRegistry

public static enum PromqlFunctionRegistry.CounterSupport
extends Enum<PromqlFunctionRegistry.CounterSupport>

Describes whether a PromQL function supports counter metric types.

This is an ES|QL implementation detail — in real PromQL, all functions work with any numeric type. ES|QL distinguishes counter types from plain numerics internally, and some ESQL functions only accept one or the other.
