How to configure the generation strategy of primary key ID for a single table

[poppop9]

This is the official document regarding the configuration of a single table:

rules:
- !SINGLE
  tables:
    # MySQL 风格
    - ds_0.t_single # 加载指定单表
    - ds_1.* # 加载指定数据源中的全部单表
    - "*.*" # 加载全部单表
    # PostgreSQL 风格
    - ds_0.public.t_config
    - ds_1.public.*
    - ds_2.*.*
    - "*.*.*"
  defaultDataSource: ds_0 # 默认数据源，仅在执行 CREATE TABLE 创建单表时有效。缺失值为空，表示随机单播路由。

I need to configure the generation strategy for the primary key of a single table now. How should I configure it?

Why not use database's generate primary key way?

Because my sharding tables are all generated using ShardingSphere's snowflake algorithm with primary key IDs:

    defaultKeyGenerateStrategy: # 默认的主键生成策略
      column: id
      keyGeneratorName: SNOWFLAKE

So I want to maintain consistency, otherwise I'll have to manually implement a snowflake algorithm。Thank you for your reply

Only sharding table need to distributed primary key
