Dear Wiki user, You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.
The "Operations" page has been changed by MakiWatanabe. The comment on this change is: Update cli command syntax at Replication section. http://wiki.apache.org/cassandra/Operations?action=diff&rev1=88&rev2=89 -------------------------------------------------- Reducing replication factor is easily done and only requires running cleanup afterwards to remove extra replicas. To update the replication factor on a live cluster, forget about cassandra.yaml. Rather you want to use '''cassandra-cli''': - update keyspace Keyspace1 set replication_factor = 3; + update keyspace Keyspace1 with replication_factor = 3; === Network topology === Besides datacenters, you can also tell Cassandra which nodes are in the same rack within a datacenter. Cassandra will use this to route both reads and data movement for Range changes to the nearest replicas. This is configured by a user-pluggable !EndpointSnitch class in the configuration file.
