[jira] [Created] (HDDS-8748) Reduce DN IO times when deleteChunk (FilePerBlockStrategy)

ChenXi created HDDS-8748:
----------------------------

             Summary: Reduce DN IO times when deleteChunk (FilePerBlockStrategy)
                 Key: HDDS-8748
                 URL: https://issues.apache.org/jira/browse/HDDS-8748
             Project: Apache Ozone
          Issue Type: Improvement
          Components: Ozone Datanode
            Reporter: ChenXi
            Assignee: ChenXi


When deleting a file, DN will check whether the  Block file to be deleted exists or not in the `FilePerBlockStrategy#deleteChunk`. 
This step of checking for the existence of a Block file can be omitted, and basically does not change the behavior of `FilePerBlockStrategy#deleteChunk`. 
This can reduce the IO-times of `FilePerBlockStrategy#deleteChunk`
