Example 1 with SuperRow

use of me.prettyprint.hector.api.beans.SuperRow in project gora by apache.

the class CassandraStore method addSuperColumns.

/**
   * When we add supercolumns, Gora keys are mapped to Cassandra partition keys only. 
   * This is because we follow the Cassandra logic where column family data is 
   * partitioned across nodes based on row Key.
