feature is enabled. By default, on a new cache

'key-to-partition' and 'partition-to-node'. The

each cache put/get request occurs and the
+ * 'key-to-partition' mapping will also be calculated on the client side.

+ * The case described above will not be possible (and in turn partition
awareness won't work) when a custom {@link AffinityFunction} or
+ * a {@link AffinityKeyMapper} was previously used for a cache creation.
The affinity function factory is used to solve this issue.
+ * All 'partition-to-node' mappings will still be requested from a server
node, however, if a custom affinity function or a custom
+ * affinity key mapper was used the affinity function produced by this
factory will calculate mapping a key to a partition.
+ *
+ * These key to partition mapping functions produced by the factory are
used only for local calculations, they will not
+ * be passed to a server node.
+ *
+ * This factory accepts as parameters a cache name and the number of cache
partitions received from a server node and produces
+ * key to partition mapping functions.
