Description

框架中有两个地方需要创建唯一主键。 分别是:事务组 GroupId值的创建 与 事务日志中id的主键策略。数据类型 groupId:string id:long

groupid格式未必一定是string，也可以修改成lang类型。但是要保证全局环境中的唯一性

Contributor guide

Research direction
Investigate the current ID generation mechanisms for GroupId and transaction log id. Consider using Snowflake or similar algorithms to ensure global uniqueness. Evaluate the impact of changing GroupId type from string to long.
