Hi @tiancaiamao. Thanks for your PR.

PRs from untrusted users cannot be marked as trusted with /ok-to-test in this repo meaning untrusted PR authors can never trigger tests themselves. Collaborators can still trigger tests on the PR using /test all.

I understand the commands that are listed here.

It's OK to fix my comments in next PR or ignore them @tiancaiamao

[tiancaiamao]

This commit could make the login process slower, because now we need to load the users data. And also some scenario like show grants for some other users.

The general DDL/DML cases should not be affected, this just affects a minority of privileges related.
