Examples of Keyspace

com.fasterxml.clustermate.api.KeySpace
Entity that represents subset of key hashes used for finding nodes that are responsible for handling piece of content with given key hash. Space is defined with a single integer value, length, covering indexes [0, length-1[.
Logically key space is circular, meaning that all {@link KeyRange}s are consecutive by using wrapping at the end of key hash range.
