我创建了一个KEYSPACE和一个TABLE,其中uuid列为主键,timestamp列使用索引.所有这些都成功如下图所示:

cassandra@cqlsh:my_keyspace> insert into my_test ( id, insert_time, value ) values ( uuid(), '2015-03-12 09:10:30', '111' );
cassandra@cqlsh:my_keyspace> insert into my_test ( id, insert_time, value ) values ( uuid(), '2015-03-12 09:20:30', '222' );
cassandra@cqlsh:my_keyspace> select * from my_test;

 id                                   | insert_time              | value
--------------------------------------+--------------------------+-------
 9d7f88bc-5cb9-463f-b679-fd66e6469eb5 | 2015-03-12 09:20:30+0000 |   222
 69579f6f-bf88-493b-a1d6-2f89fac25650 | 2015-03-12 09:10:30+0000 |   111

(2 rows)

现在查询

cassandra@cqlsh:my_keyspace> select * from my_test where insert_time = '2015-03-12 09:20:30';

 id                                   | insert_time              | value
--------------------------------------+--------------------------+-------
