             Summary: OM rocksdb uses a lot of space
                 Key: HDDS-8128
                 URL: https://issues.apache.org/jira/browse/HDDS-8128
             Project: Apache Ozone
          Issue Type: Improvement
          Components: OM
            Reporter: Tsz-wo Sze


In a multipart upload test, the key "testKey" had 1000-parts with 8KB each.  
The same key was uploaded 10 times sequentially (i.e. it overwrote the previous 
upload) in a newly formatted cluster.  The replication was 3, so the total raw 
size of the key is ~ 24 MB.  After the test has completed, OM rocks db uses ~ 
7.5 GB.
