BootStrapper

public BootStrapper(java.net.InetAddress address,
                    java.util.Collection<Token> tokens,
                    TokenMetadata tmd)

Method Detail

bootstrap

public com.google.common.util.concurrent.ListenableFuture<StreamState> bootstrap(StreamStateStore stateStore,
                                                                                 boolean useStrictConsistency)

getBootstrapTokens

public static java.util.Collection<Token> getBootstrapTokens(TokenMetadata metadata)
                                                      throws ConfigurationException

if initialtoken was specified, use that (split on comma). otherwise, if num_tokens == 1, pick a token to assume half the load of the most-loaded node. else choose num_tokens tokens at random

Throws:

ConfigurationException

getRandomTokens

public static java.util.Collection<Token> getRandomTokens(TokenMetadata metadata,
                                                          int numTokens)
