因为我一直想用Cassandra来存储我们的数字电表中的数据，按照之前的文章(getting-started-time-series-data-modeling )的介绍，Cassandra真的和适合用于存储time series类型的数据，那么我就想要弄清楚，对于下面这张表
CREATE TABLE temperature ( weatherstation_id text, event_time timestamp, temperature text,PRIMARY KEY (weatherstation_id,event_time));
在插入了下面这些数据之后，他内部究竟是怎么存储的？
INSERT INTO temperature(weatherstation_id,event_time,temperature) VALUES ('1234ABCD','2013-04-03 07:01:00','72F');INSERT INTO temperature(weatherstation_id,event_time,temperature) VALUES ('1234ABCD','2013-04-03 07:02:00','73F');INSERT INTO temperature(weatherstation_id,event_time,temperature) VALUES ('1234ABCD','2013-04-03 07:03:00','73F');INSERT INTO temperature(weatherstation_id,event_time,temperature) VALUES ('1234ABCD','2013-04-03 07:04:00','74F');
如果按
