如何使用python/thrift插入超级列？

Question

使用python/thrift接口，我试图插入一个超级列，就像WTF is a Supercolumn..中的注释示例一样

我已经创建了超级列，并发现应该使用batch mutate来插入它。但我不知道如何创建突变，以及如何设置键和超级列类型

keyspace = "Keyspace1"

col1 = Column(name = "commenter", value = "J Doe", timestamp = time.time())
col2 = Column(name = "email", value = "jdoe@example.com", timestamp = time.time())

sc = SuperColumn(name = str(uuid.uuidl()), [col1, col2])

# i am guessing the missing code goes here

mutation = Mutation(column_or_supercolumn = sc?)
client.batch_mutate(keyspace, mutation, ConsistencyLevel.ZERO)

我会用pycassa之类的东西来让生活更轻松，但是像：

keyspace = "Keyspace1"
tableName = "Super1"
key = "jdoe"
col1 = Column(name = "commenter", value = "J Doe", timestamp = time.time())
col2 = Column(name = "email", value = "jdoe@example.com", timestamp = time.time())

newData = [Mutation(ColumnOrSuperColumn(None,
                             SuperColumn(str(uuid.uuidl()),
                                        [col1, col2])))]
dataMap = {key : {tableName : newData}}

client.batch_mutate(keyspace=keyspace,
                    mutation_map=dataMap,
                    consistency_level=ConsistencyLevel.ZERO)
