src/meta/app/src/schema/lock.rs line 149 at r1 (raw file):

        if self.table_ids.is_empty() {
            let table_lock_prefix =
                format!("{}/{}/", TableLockKey::PREFIX, self.tenant.tenant_name());

Do no use ::PREFIX directly, use the structured key to build a prefix with:

let ident = TableLockKey::new(self.tenant.clone(), 0, 0);
let prefix = DirName::new_with_level(lock, 2).dir_name_with_slash();

And it is prone to bug using this method to build both two levels prefix string and one level prefix string.
There should be another method to build a one level prefix string.

👆🏻This method builds two different kinds of keys. There should be two methods for two kinds of keys.

Done.
