Part of #27065 This reduces the usage of `db.DefaultContext`. I think I've got enough files for the first PR. When this is merged, I will continue working on this. Considering how many files this PR affect, I hope it won't take to long to merge, so I don't end up in the merge conflict hell. --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
