Examples of org.apache.cassandra.thrift.ColumnPath

org.apache.cassandra.thrift.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.

        for (int nRows = minRow; nRows < maxRow; nRows++)
        {

            ColumnPath col = new ColumnPath("Standard1").setSuper_column((ByteBuffer)null).setColumn("col1".getBytes());
            ColumnParent parent = new ColumnParent("Standard1").setSuper_column((ByteBuffer)null);


            Collection<InetAddress> endpoints = tester.ringCache.getEndpoint(row);
            InetAddress firstEndpoint = endpoints.iterator().next();
            System.out.printf("hosts with key %s : %s; choose %s%n",
