What you think should happen instead

Pretty sure #649 has nothing to do with resource group. It seems a unstable case of resource group.

memory usage is acceptable between 0.00 ~ 0.01 . so let we change the .sql/.out

This problem has been happening more often recently.

I saw this in other PRs/commits on main branch.

If the test case is not stable, how about we disable it?
