> Currently in listStatus we make multiple getFileStatus calls. This can be
> optimized by converting to a single rpc call for listStatus.
> Also currently listStatus has to traverse a directory recursively in order to
> list its immediate children. This happens because in OzoneManager all the
> metadata is stored in rocksdb sorted on keynames. The Jira also aims to fix
> this by using seek api provided by rocksdb.
