Interface ClientPartitionAwarenessMapper

public interface ClientPartitionAwarenessMapper

This function calculates the cache key to a partition mapping for each cache key. It is used only for local calculation on a client side.

When the ClientConfiguration.isPartitionAwarenessEnabled() and the cache was created with a custom AffinityFunction or a AffinityKeyMapper this function will be used to calculate mappings. Be sure that a key maps to the same partition produced by the AffinityFunction.partition(Object) method.
