   > @fuchaohong Hi, IIUC the `dfsused` will be refreshed periodically. Do you 
meet any issues about this metric? Thanks.
   @Hexiaoqiao Indeed, the dfsused metric is corrected periodically, but the 
cycle is very long. Currently, when there are too many append operations, 
dfsused may expand abnormally, not reflecting the actual usage accurately. 
Thanks.
