Hi,
I am trying to use batch_mutate() with PHP Thrift. I was getting the following error. *Fatal error*: Uncaught exception 'cassandra_InvalidRequestException' in CORE/php/phpcassa/thrift/packages/cassandra/Cassandra.php:4869 Stack trace: #0 CORE/php/phpcassa/thrift/packages/cassandra/Cassandra.php(777): cassandra_Cassandra_batch_mutate_result->read(Object(TBinaryProtocolAccelerated)) The version is *Cassandra 0.6* $client->batch_mutate($this->keyspace, $mutation_map, $this ->write_consistency_level); Here is my mutation map, Any idea on what was going wrong. ------------------------------ array(1) { ["cache_pages"]=> array(1) { ["Page"]=> array(2) { [0]=> object(cassandra_Mutation)#32 (2) { ["column_or_supercolumn"]=> object(cassandra_ColumnOrSuperColumn)#31 (2) { ["column"]=> object(cassandra_Column)#30 (3) { ["name"]=> string(2) "id" ["value"]=> int(1) ["timestamp"]=> int(1274949222) } ["super_column"]=> NULL } ["deletion"]=> NULL } [1]=> object(cassandra_Mutation)#35 (2) { ["column_or_supercolumn"]=> object(cassandra_ColumnOrSuperColumn)#34 (2) { ["column"]=> object(cassandra_Column)#33 (3) { ["name"]=> string(4) "hash" ["value"]=> string(15) "d930517baf47237" ["timestamp"]=> int(1274949222) } ["super_column"]=> NULL } ["deletion"]=> NULL } } } } ------------------------------ Thanks in Advance, Moses.
