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).

Specified by:

size 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.
