The "MultiTenant" page has been changed by EdAnuff. The comment on this change is: Added mention of Hector virtual keyspaces. http://wiki.apache.org/cassandra/MultiTenant?action=diff&rev1=22&rev2=23 -------------------------------------------------- * The distinction from keyspaces is that a namespace would be completely transparent to the user: the existence of namespaces would not be exposed. It might be returned by the authentication backend on login, and prefixed to keyspaces transparently. * JMX authentication without breaking nodetool - currently if you try to use JMX authentication, some of the Cassandra tools won't connect properly. * Perhaps provide a way to throttle certain operations, maybe useful outside the scope of multi-tenancy. Voldemort, for example, uses a [[http://github.com/voldemort/voldemort/blob/master/src/java/voldemort/utils/EventThrottler.java|throttler]] for operations that quickly iterate over all the data of a node, such as a rebalance. + * The Hector java client for Cassandra has experimental support for a “Shared Keyspace, Shared Column Families” multi-tenancy model that allows for application-level virtual keyspaces [[https://github.com/rantav/hector/wiki/Virtual-Keyspaces|Virtual keyspaces in Hector]].
