Description

请问下，mycat 双主模式下主键能用mycat 自带的全局或本地时间戳生成方式么，内置的主键生成机制在双主下，id有可能重复么，还是需要一个全局的id生成器来做？

Contributor guide

Research direction
Research how Mycat handles primary key generation in dual master mode. Check the documentation and source code for the global and local timestamp generation methods. Determine if IDs could duplicate and if an external ID generator is needed.
