Hi @HuSharp. Thanks for your PR.

I'm waiting for a tikv member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

What is the difference between backgroundMetricsFlush and persistLoop?

persistLoop function requires a look at the code to know that it is a goroutine and is not used anywhere else.
To avoid adding logpanic to confuse people, it was changed to this
