public static interface ConsistentHashingRouter.ConsistentHashable
hashMapping
when
constructing the ConsistentHashingRouter
the messages need to implement this interface to define what
data to use for the consistent hash key. Note that it's not
the hash, but the data to be hashed.
If returning an Array[Byte]
or String it will be used as is,
otherwise the configured Serializer
will be applied to the returned data.
If messages can't implement this interface themselves,
it's possible to wrap the messages in
ConsistentHashingRouter.ConsistentHashableEnvelope
,
or use ConsistentHashingRouter.ConsistentHashableEnvelope
