Dear Wiki user, You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.
The "MultiTenant" page has been changed by JonathanEllis: http://wiki.apache.org/cassandra/MultiTenant?action=diff&rev1=24&rev2=25 * Implement a weighted scheduler - e.g. for dev/prod accounts on the same cluster [[https://issues.apache.org/jira/browse/CASSANDRA-1485|CASSANDRA-1485]] == Ideas under consideration == + * Compaction fairness: currently, compaction makes no attempt to balance attention across multiple CFs * Include memory usage in "load" considerations for load balancing: ColumnFamilies with higher cache requirements have memory to consider. * Namespaces - in a multi-tenant use case, each user might like to have a keyspace XYZ for whatever reason. So it might be nice to have namespaces so that keyspace XYZ could be specific to their user. Ideally this would be an option that would not affect those that don't use namespaces. * 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.
