python - cassandra中的重复行

Question

我有一种方法将数据发布到 Cassandra 表中。不知何故，我能够（有时）添加不应该发生的重复行。以下是我为此编写的方法。我正在检查该名称是否已经存在，如果存在，则不应发布任何数据。

有什么明显的我失踪了吗？

    print(args)
    jm = Jenkins()
    #print(json.dumps(args, sort_keys=True, indent=4))

    for i in args:
        jm.name = i['fullDisplayName']
        jm.result = i['result']
        jm.jobnumber = str(i['id'])
        jm.executor = i['executor']
        jm.duration = str(i['duration'])
        jm.time_stamp = str(i['timestamp'])
        jm.url = i['url']
        jm.id = str(uuid.uuid4())

        check_if_table_is_empty = len(Jenkins.objects.all())
        if (check_if_table_is_empty is 0):
                Jenkins.create(name=jm.name, result=jm.result, jobnumber=jm.jobnumber, executor=jm.executor,
                                      duration=jm.duration, time_stamp=jm.time_stamp, url=jm.url, id=jm.id)
                return jm.id
        else:
                for data in Jenkins.objects.all():
                        if (data['name'] == jm.name):
                                return data['id']
                        else:
                                jm.save()
                                return jm.id
