Summary: [hsync] Optimize FilePerBlockStrategy.writeChunk()
Key: HDDS-10055
URL: https://issues.apache.org/jira/browse/HDDS-10055
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Wei-Chiu Chuang
Looking at async profile report of a hsync intensive workload, a quite
noticeable CPU overhead (3%) can be eliminated.
It would be great to cache the File object, and don't check if the file exists
or not every single time.
