分库分表主键生成 - 自增主键雪花类算法分段

还有一种常见的方案也叫自增，不过这种自增有点特殊，它是设置了步长的自增。经过分库分表后我有10个表，可以让每个表按照步长生成自增ID，比如第一个表生成的是1,11,21,31这种ID，第二个表生成的是2,12,22,32这种ID，这种方案的关键是表内部自增。这种方案非常简单，而且本身我们在应用层面...

数据库分库分表常见算法

哈希取模算法：原理：通过对某个字段（如用户ID）的哈希值进行取模运算，将数据均匀地分布到不同的库或表中。使用场景：适用于数据量大且分布均匀的场景，常用于用户中心等系统。优点：数据分布均匀，有利于负载均衡。横向扩展方便，只需增加新的表或数据库实例。缺点： ...

DRDS数据库，建表语句中进行分库分表时的hash算法实现方式？

DRDS数据库，建表语句中进行分库分表时的hash算法：dbpartition by hash(id) tbpartition by hash(id) tbpartitions 8; 我这个id是字符串类型，drds的hash算法是怎么计算出路由键值的呢，取模运算获得具体哪个分库的分表都是根据这个键值操作的
