org.axonframework.commandhandling.distributed.ConsistentHash
Basic implementation of a Consistent Hashing algorithm, using the MD5 algorithm to build the hash values for given keys and node names. It contains some basic operation to add nodes and remove nodes given a set of known remaining members.
Each node contains a Set of supported Commands (as a set of the fully qualified names of payload types). When performing a lookup for a given command, only nodes that support the payload type of the command are eligible. @author Allard Buijze @since 2.0
