Description:
This node only participates in MGR voting arbitration, does not store user data and binary logs/relay logs, and does not need to perform DML operations. 

Therefore, the high availability of MGR in three nodes can be achieved at the cost of nearly two servers

How to repeat:
null

Suggested fix:
null

Hello Ye Jinrong,

Thank you for the feature request!
