Package com.linkedin.venice.stats.metrics

Interface AsyncMetricResolvers.LiveStateResolverTwoEnums<E1 extends Enum<E1> & VeniceDimensionInterface,E2 extends Enum<E2> & VeniceDimensionInterface,S>

Type Parameters:
E1 - the first enum dimension type
E2 - the second enum dimension type
S - the backing state type (any reference type — never inspected beyond null-check)
Enclosing class:
AsyncMetricResolvers
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public static interface AsyncMetricResolvers.LiveStateResolverTwoEnums<E1 extends Enum<E1> & VeniceDimensionInterface,E2 extends Enum<E2> & VeniceDimensionInterface,S>
Resolves the backing state for an (e1, e2) dimension pair, or null when the pair is dormant. The null return is the liveness signal used by AsyncMetricEntityStateTwoEnums: dormant pairs are not observed by the SDK and therefore do not count against the per-instrument cardinality cap.
