Saga状态机实例表为什么不用自增id作为主键？


请问下这两张表为什么不用自增id作为主键？

The issue only provides an image of two Saga state-machine tables and asks why they do not use an auto-incrementing primary key; no files, tests, or entry points are named. Start by locating the corresponding schema definitions and confirm the intended primary-key rationale with maintainers. Done would require a documented explanation or a clearly agreed schema change.
