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.
