mysql 分库分表怎么实现

spring:
  shardingsphere:
    datasource:
      names: ds0, ds1
      ds0:
        type: com.zaxxer.hikari.HikariDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        jdbc-url: jdbc:mysql://localhost:3306/db0?serverTimezone=UTC&useSSL=false&useUnicode=true&characterEncoding=UTF-8
        username: root
        password: root
      ds1:
        type: com.zaxxer.hikari.HikariDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        jdbc-url: jdbc:mysql://localhost:3306/db1?serverTimezone=UTC&useSSL=false&useUnicode=true&characterEncoding=UTF-8
        username: root
        password: root
    sharding:
      tables:
        t_order:
          actual-data-nodes: ds$->{0..1}.t_order_$->{0..1}
          table-strategy:
            inline:
              sharding-column: order_id
              algorithm-expression: t_order_$->{order_id % 2}
          key-generator:
            column: order_id
            type: SNOWFLAKE
