> Currently delete file is to get all the keys in the directory, and then delete one by one. And the same with rename. This makes for poor performance.
> By tested the deletion path with 100,000 files, which took 3718.70 sec. And rename it took 7327.936.
> We plan to change this part to a batch operation to improve performance.
