Interface PartitioningStrategy<K>

  • Type Parameters:
    K - key type
    All Superinterfaces:
    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.

    public interface PartitioningStrategy<K>
    PartitioningStrategy allows keys to be located on the same member. This causes related data to be stored in the same location. (See data-affinity.)
