Subject [Cassandra Wiki] Update of "StorageConfiguration" by StuHood
Date Thu, 22 Apr 2010 03:28:15 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.

The "StorageConfiguration" page has been changed by StuHood.


  <ClusterName>Test Cluster</ClusterName>
+ == Authenticator ==
+ ''[New in 0.6:''
+ Allows for pluggable authentication of users, which defines whether it is necessary to call
the Thrift 'login' method, and which parameters are required to login. The default '!AllowAllAuthenticator'
does not require users to call 'login': any user can perform any operation. The other built
in option is '!SimpleAuthenticator', which requires users and passwords to be defined in property
files, and for users to call login with a valid combo. 
+ Example:
+ {{{
+ <Authenticator>org.apache.cassandra.auth.SimpleAuthenticator</Authenticator>
+ }}}
+ '']''
  == Keyspaces and ColumnFamilies ==
  Keyspaces and {{{ColumnFamilies}}}: A {{{ColumnFamily}}} is the Cassandra concept closest
to a relational table.  {{{Keyspaces}}} are separate groups of {{{ColumnFamilies}}}.  Except
in very unusual circumstances you will have one Keyspace per application.
