             Summary: Optimize replication type and creation time calculation in S3 MPU list call
                 Key: HDDS-2131
                 URL: https://issues.apache.org/jira/browse/HDDS-2131
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
            Reporter: Elek, Marton


Based on the review from [~bharatviswa]:

{code}
 hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/om/KeyManagerImpl.java
                  metadataManager.getOpenKeyTable();

              OmKeyInfo omKeyInfo =
                  openKeyTable.get(upload.getDbKey());
{code}

{quote}Here we are reading openKeyTable only for getting creation time. If we can have this information in omMultipartKeyInfo, we could avoid DB calls for openKeyTable.

To do this, We can set creationTime in OmMultipartKeyInfo during initiateMultipartUpload . In this way, we can get all the required information from the MultipartKeyInfo table.

And also StorageClass is missing from the returned OmMultipartUpload, as listMultipartUploads shows StorageClass information. For this, if we can return replicationType and depending on this value, we can set StorageClass in the listMultipartUploads Response.
