Interface PartitionPredicate<K,V>

Type Parameters:

K - type of the entry key

V - type of the entry value

All Superinterfaces:

Predicate<K,V>, Serializable

public interface PartitionPredicate<K,V>
extends Predicate<K,V>

A Predicate that restricts the execution of a Predicate to a single partition. This can help to speed up query execution since only a single instead of all partitions needs to be queried. This predicate only has effect if used as an outermost predicate.
