Examples of org.apache.cassandra.service.ColumnPath

org.apache.cassandra.service.ColumnPath
The ColumnPath is the path to a single column in Cassandra. It might make sense to think of ColumnPath and ColumnParent in terms of a directory structure. ColumnPath is used to looking up a single column. @param column_family. The name of the CF of the column being looked up. @param super_column. The super column name. @param column. The column name.

        String table = "Keyspace1";
        for (int nRows=1; nRows<10; nRows++)
        {
            String row = "row" + nRows;
            ColumnPath col = new ColumnPath("Standard1", null, "col1".getBytes());


            List<InetAddress> endPoints = ringCache.getEndPoint(row);
            String hosts="";
            for (int i = 0; i < endPoints.size(); i++)
                hosts = hosts + ((i > 0) ? "," : "") + endPoints.get(i);
