---------------------------------
Summary: Support topology awareness in pipeline choose policy
Key: HDDS-9867
URL: https://issues.apache.org/jira/browse/HDDS-9867
Project: Apache Ozone
Issue Type: Improvement
Components: DN, SCM
Reporter: Ivan Andika
From [https://github.com/apache/ozone/pull/5666#discussion_r1410542795]
[~XiChen] suggested:
"Maybe can add a new subclass for {{PipelineChoosePolicy}} (such as {{{}NearestPipelineChoosePolicy{}}}) to "sort" the datanode when {{{}choosePipeline{}}}? This would get a better results."
This will be a useful choose policy so that the pipeline can be closest to the client during block allocation and writing.
