Package com.hazelcast.partition

Interface PartitioningStrategy<K>

Type Parameters:
K - key type
All Superinterfaces:
Serializable
All Known Implementing Classes:
AttributePartitioningStrategy, DefaultPartitioningStrategy, StringAndPartitionAwarePartitioningStrategy, StringPartitioningStrategy
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 interface PartitioningStrategy<K> extends Serializable
PartitioningStrategy allows keys to be located on the same member. This causes related data to be stored in the same location. (See data-affinity.)
