Subject [Cassandra Wiki] Update of "DataModelv2" by ronaldmathies
Date Fri, 16 Apr 2010 10:32:58 GMT
Dear Wiki user,

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

The "DataModelv2" page has been changed by ronaldmathies.


  it adds an extra layer in your data structure, instead of having only a row which consists
of a key and a list of columns we can now have a row
  which consists of a key and a list of super columns which by itself has keys and per key
a list of columns.
- == !ColumnFamily containing !SuperColumns ==
+ == ColumnFamily containing SuperColumns ==
  A !ColumnFamily which contains !SuperColumns isn't that much different from a !ColumnFamily
containing Columns, instead of having a row consisting of Columns we have rows consisting
of !SuperColumns.
