我已经编写了一个java程序来对我的cassandra数据库执行upsert操作，它由一个具有多个列表的表组成，我正在使用java代码尝试同时写入多个这样的列表假设一次写入10个，但是，当我查看我的cassandra表时，列表中的值并没有以同步的方式存储，一些值从原始位置切换位置，尽管每个值的时间戳都是正确的，但不知何故列表没有以正确的顺序表示。共享文件和示例代码，这将有助于识别问题。

String newInsertQuery1 =  "UPDATE events.generated_event SET attributes = ['100'] + attributes, channels = ['100'] + channels, " + "event_types = ['100'] + event_types, ip = ['100'] + ip, library_info = ['100'] + library_info, property_ids = ['100'] + property_ids," + "texts = ['100'] + texts, user_agent = ['100'] + user_agent WHERE profile_id = '1111' AND project_id = '5bbc83f4bf52016962b695da' AND bucket_id = 1555977600000"; 

String newInsertQuery2 =  "UPDATE events.generated_event SET attributes = ['300'] + attributes, channels = ['300'] + channels, " + "event_types = ['300'] + event_types, ip = ['300'] + ip, library_info = ['300'] + library_info, property_ids = ['300'] + property_ids," + "texts = ['300'] + texts, user_agent = ['300'] + user_agent WHERE profile_id = '1111' AND project_id = '5bbc83f4bf52016962b695da' AND bucket_id = 1555977600000";

String newInsertQuery3 =  "UPDATE events.generated_event SET attributes = ['400'] + attributes, channels = ['400'] + channels, " + "event_types = ['400'] + event_types, ip = ['400'] + ip, library_info = ['400'] + library_info, property_ids = ['400'] + property_ids," + "texts = ['400'] + texts, user_agent = ['400'] + user_agent WHERE profile_id = '1111' AND project_id = '5bbc83f4bf52016962b695da' AND bucket_id = 1555977600000";

类似地，查询4、5、6、7。
我让许多线程同时运行，每个线程执行一个查询。
扩展结果：

所附的图像由sstabledump命令的输出组成，如您所见，每行中的tstamp值（比如800）是相同的，但当我对此表执行读取时，打印给我的值不会被排序，它们的打印顺序与sstabledump中写入的顺序相同
