Method Detail

getPartitioner

public IPartitioner getPartitioner()

Specified by:

getPartitioner in interface RingPosition<Token>

Specified by:

getPartitioner in class Token

getHeapSize

public long getHeapSize()

Specified by:

getHeapSize in class Token

increaseSlightly

public Token increaseSlightly()

Description copied from class: Token

Returns a token that is slightly greater than this. Used to avoid clashes between nodes in separate datacentres trying to use the same token via the token allocation algorithm.

size

public double size(Token next)

Description copied from class: Token

Returns a measure for the token space covered between this token and next. Used by the token allocation algorithm (see CASSANDRA-7032).
