The parameters dynamicUpdateInterval, dynamicResetInterval and dynamicBadnessThreshold can be specified individually to update the parameters of the dynamic snitch during runtime.

Parameters:

epSnitchClassName - the canonical path name for a class implementing IEndpointSnitch

dynamic - boolean that decides whether dynamicsnitch is used or not - only valid, if epSnitchClassName is specified

dynamicUpdateInterval - integer, in ms (defaults to the value configured in cassandra.yaml, which defaults to 100)

rebuild

void rebuild(java.lang.String sourceDc)

Initiate a process of streaming data for which we are responsible from other nodes. It is similar to bootstrap except meant to be used on a node which is already in the cluster (typically containing no data) as an alternative to running repair.

Parameters:

sourceDc - Name of DC from which to select sources for streaming or null to pick any node

rebuild

void rebuild(java.lang.String sourceDc,
             java.lang.String keyspace,
             java.lang.String tokens,
             java.lang.String specificSources)

Same as rebuild(String), but only for specified keyspace and ranges.

Parameters:

sourceDc - Name of DC from which to select sources for streaming or null to pick any node

keyspace - Name of the keyspace which to rebuild or null to rebuild all keyspaces.

tokens - Range of tokens to rebuild or null to rebuild all token ranges. In the format of: "(start_token_1,end_token_1],(start_token_2,end_token_2],...(start_token_n,end_token_n]"

bulkLoad
