<p> 以上范例是用户登陆记录的分表分库策略，一年一个库，一个库中365张表，每天一个表。由于分表是根据记录的创建时间作为策略分表，因此策略接口中的public String getTable(String table, Serializable primary) 方法不能实现，因为根据主键id无法确定到数据库表。</p>

<p> 以上范例是用户登陆记录的分表分库策略，一年一个库，一个库中365张表，每天一个表。由于分表是根据记录的创建时间作为策略分表，因此策略接口中的public String getTable(String table, Serializable primary) 方法无法实现，根据主键id无法判断出数据所在的数据库表。若有根据ID获取单条记录的需求，则需要变更loginid的生成规则，可以改成UUID+createtime，如下：</p>

<p> 如上范例，若需要分表策略的三个接口均得到实现，需要对主键ID的生成规则进行一定的设计。并不是所有的数据表都需要进行全量查询或单个记录查询，开发人员可根据使用场景来设计分表策略和主键生成规则。事实上用户登录记录很少场景需要查询单个记录的， 但是常见的场景是查询单个用户的登录列表。上面的范例无法满足查询单个用户的登录信息需求，而分表策略又只能根据一种规则生成，因此需要按用户维度存在另外一张表中。</p>

<p> 如上，表LoginUserRecord只存储用户ID与登录信息ID的关联关系，以用户ID取模100进行hash存储，获取用户登录列表时，先查询LoginUserRecord一页的数据，再根据loginid查询LoginRecord实体。常见的分表策略是时间和主键hash，例如用户信息表采用主键hash分表：</p>

<p> CacheSource同Memcached类似，像一个带有过期功能地Map容器，存放key-value数据。常见的使用场景就是存放HTTP的Session信息。Redkale把用户会话信息数据当做业务数据处理，而不是接入层的数据。WebSocket的连接态数据也是用CacheSource存储。key为WebSocket的groupid，value为WebSocket服务端节点的IP地址列表。</p>
