What problem does this PR solve?
Fixes #8427
What is changed and how it works?
When a
GRANT
,DROP USER
,CREATE USER
is run, TiDB will asynchronously notify peers via etcd. The problem is that for the test suite, mocktikv (and MySQL compatibility) it is required to runFLUSH PRIVILEGES
synchronously. This is because changes are expected to apply immediately.Check List
