JAVA API
Mapping from message to the data to use for the consistent hash key.
Note that it's not the hash that is to be returned, but the data to be
hashed.
May return null to indicate that the message is not handled by
this mapping.
If returning an Array[Byte] or String it will be used as is,
otherwise the configured akka.akka.serialization.Serializer
will be applied to the returned data.
