如果只想允许用户删除数据，不能让他删除数据结构 即timesries，似乎做不到

我如果只想允许用户删除数据，不能让他删除数据结构 即timesries，似乎做不到，
赋于用户delete timesries权限后，什么结构和数据都能删除。这不合理

Start by reproducing the reported behavior: grant a user delete permission for time-series data and compare deletion of data with deletion of the time-series structure. Trace the Java authorization path that handles delete privileges. Done means users can delete data without being able to delete the corresponding schema, with tests covering both permissions.
