场景大概是：需要记录大量用户的操作Action，需要查询用户最新的行为[[BR]]

采用数据库设计有类似的SQL
{{{
SELECT id, name, stamp FROM actions WHERE userid = 1
ORDER BY stamp DESC LIMIT 10 OFFSET 20;
NSERT INTO actions (id, userid, name, stamp) VALUES (newid(), 1, 'Joe User', epoch());
}}}

如果采用HBASE设计，ROW设计为<userid><reverse_order_stamp><actionid>
