    Hmm...there is another reason, indeed the mainly performance overhead is the `seek()`.
Even though we use the `deleteRange()` to implement this, we also need to get the last key
of the entries which means we also need to iterate all the entries. So, the `deleteRange()`
approach seems won't make a obvious lift then this approach.
