Is it still working? We can ship it in 0.3.1 next week.

Hey Dennis,
yes, I was catching up with @waynexia a couple of days ago regarding the question that I had.
I'm clear now and will try allocating some time during the weekend.

I've addressed code review suggestions.
Thanks for pointing me out the paste crate, I found it useful.
I see that the test_alter_region_with_reopen test failed, I've double checked it works locally fine. Could it be the flaky behaviour? Would you mind just restart the action for me please?

Great work. Looks like it's a known bug, will be fixed at #1759
