Hi @GMHDBJD. 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.

Rest LGTM

Maybe change the naming to express fast create table & db

[GMHDBJD]

because our variable is tidb_enable_fast_create_table, so I think this func name is better than GetFastCreateTableAndDBInitialized.
