Method Detail

getKeyForNode

java.lang.String getKeyForNode(MemcachedNode node,
                             int repetition)

Returns a uniquely identifying key, suitable for hashing by the KetamaNodeLocator algorithm.

Parameters:

node - The MemcachedNode to use to form the unique identifier

repetition - The repetition number for the particular node in question (0 is the first repetition)

Returns:

The key that represents the specific repetition of the node

getNodeRepetitions

int getNodeRepetitions()

Returns the number of discrete hashes that should be defined for each node in the continuum.

Returns:

a value greater than 0
