batch_mutate - PHP

[Ken McCarthy <km...@gridironsoftware.com>]

Any examples on how to set up the mutation_map ?

The best I can figure out is:

array(1) {
  ["195f224d2e8d15d215726590754e3ff3"]=>
  array(1) {
    ["time"]=>
    array(8) {
      [0]=>
      object(cassandra_Mutation)#18 (2) {
        ["column_or_supercolumn"]=>
        object(cassandra_ColumnOrSuperColumn)#19 (2) {
          ["column"]=>
          object(cassandra_Column)#20 (3) {
            ["name"]=>
            string(4) "user"
            ["value"]=>
            string(9) "memymo"
            ["timestamp"]=>
            int(1272399957)
          }
          ["super_column"]=>
          NULL
        }
        ["deletion"]=>
        NULL
      }

........

      [7]=>
      object(cassandra_Mutation)#39 (2) {
        ["column_or_supercolumn"]=>
        object(cassandra_ColumnOrSuperColumn)#40 (2) {
          ["column"]=>
          object(cassandra_Column)#41 (3) {
            ["name"]=>
            string(8) "interval"
            ["value"]=>
            float(5)
            ["timestamp"]=>
            int(1272399957)
          }
          ["super_column"]=>
          NULL
        }
        ["deletion"]=>
        NULL
      }
    }
  }
}


TException:  Error: Bad type in structure.

Thanks.

Hi,
Here is a working example :

    $mutation_map = array("$key"=>array("Standard1" => array()));
    for($column_name=0; $column_name<$options['numcolumns']; $column_name++)
    {
      $column = new cassandra_Column(array('name' => "$column_name", 'value'
=> 'put your data here', 'timestamp' => time()));
      $c_or_sc = new cassandra_ColumnOrSuperColumn(array('column' =>
$column));
      $mutation = new cassandra_mutation(array('column_or_supercolumn' =>
$c_or_sc));
      $mutation_map["$key"]["Standard1"][] = $mutation;
    }
    $client->batch_mutate('Keyspace1', $mutation_map,
cassandra_ConsistencyLevel::ONE);

Hope it helps.

Jordan
