[Cassandra Wiki] Update of "DataModel" by jeremyhanna

Dear Wiki user,

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

The "DataModel" page has been changed by jeremyhanna:
https://wiki.apache.org/cassandra/DataModel?action=diff&rev1=38&rev2=39

  The first component of a table's primary key is the partition key; within a partition, rows are clustered by the remaining columns of the PK.  Other columns may be indexed independent of the PK.
  
  This allows pervasive denormalization to "pre-build" resultsets at update time, rather than doing expensive joins across the cluster.
