Re: Keyspace and table/cf limits
has there been any recent discussion on multitenancy namespaces ? I think this would effectively solve the scenario -- a formalized partition-key that's enforced at the storage layer, similar to oracle's virtual private database it was on the wiki from ~ Aug 2010 http://wiki.apache.org/cassandra/MultiTenant >>>> 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. <<<< thanks !!!

cell-level security for cassandra ?

JIRA for native IAuthorizer and IAuthenticator ?

Re: cassandra 1.08 on java7 and win7
iirc, the fix for me was to add conf to the CASSANDRA_CLASSPATH var; like
so:
>>>>
:okClasspath
REM Include the build\classes\main directory so it works in development
set CASSANDRA_CLASSPATH=%CASSANDRA_HOME%\conf;
%CLASSPATH%;"%CASSANDRA_HOME%\build\classes\main";"%CASSANDRA_HOME%\build\classes\thrift"
