             Summary: Improve Deletion of FSO Paths
                 Key: HDDS-7328
                 URL: https://issues.apache.org/jira/browse/HDDS-7328
             Project: Apache Ozone
          Issue Type: Improvement
            Reporter: Xu Shao Hong
            Assignee: Xu Shao Hong


Currently, the deleting speed of FSO path is too slow.

Every time the DirectoryDeletingService executes(every 1m by default),  it 
chooses only one path from DeletedDirectroyTable and tries adding its sub-files 
and sub-dirs into the

PurgeDirectories Request. And the real deletion happens in 
OMKeyDeleteResponseWithFSO, which moved all sub-dirs into 
DeletedDirectroyTable.  

Then these sub-dirs will be chosen by the future execution of 
DirectoryDeletingService.

 

The problem is obvious, the choosing policy is too moderate and it is not 
applicable to the cluster of large scale.
