Review Comment:
@nastra Wouldn't it be safer to set the list to empty at the end of this
function? If this list isn't emptied it can lead to the same bug since it will
think it doesn't need to produce manifests in the `newDataFilesAsManifests`
method.
I don't think this is an issue right now because I expect all commits to
fail or succeed so all files to be deleted, but maybe for safety we should just
clear it?
@ConeyLiu If I understand correctly the files are only cleared once the
transaction/operation fully fails so it should clear everything at the end
right?
