smengcl opened a new pull request, #5175: URL: https://github.com/apache/ozone/pull/5175
## What changes were proposed in this pull request? A snapshot's referenced size is identical to the bucket's point-in-time `omBucketInfo.getUsedBytes()`. Note it is the size AFTER replication. - Snapshot referenced size is stored directly into `SnapshotInfoTable` during snapshot creation so as to avoid opening every single snapshot under a bucket just to display the size. - Currently referenced size can be shown under `fs -ls`: ``` bash-4.2$ ozone fs -mkdir -p ofs://om/vol1/buck2/dir3/subdir4/ bash-4.2$ ozone fs -put README.md ofs://om/vol1/buck2/dir3/subdir4/ bash-4.2$ ozone fs -createSnapshot ofs://om/vol1/buck2/ snap1 Created snapshot ofs://om/vol1/buck2/.snapshot/snap1 bash-4.2$ ozone fs -ls ofs://om/vol1/buck2/.snapshot/ Found 1 items drwxrwxrwx - hadoop hadoop 4068 2023-08-11 07:30 ofs://om/vol1/buck2/.snapshot/snap1 bash-4.2$ ``` ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-9159 ## How was this patch tested? - Tested manually in Docker compose cluster. - Tested via `testFsLsSnapshot`. -- This is an automated message from the Apache Git Service.
