Wei-Chiu Chuang updated HDDS-13704:
-----------------------------------
Parent: HDDS-13747 (was: HDDS-12940)
> Calculate pending for deletion bytes at each snapshot
> -----------------------------------------------------
>
> Key: HDDS-13704
> URL: https://issues.apache.org/jira/browse/HDDS-13704
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Sumit Agrawal
> Assignee: Priyesh K
> Priority: Major
>
> To identify how much pending overall acquired by snapshot, we can maintain
> the pending bytes to be deleted at each snapshot.
> This pendingDeletion bytes will refer the amount of bytes pending for
> deletion in deletedTable and deletedDirectoryTable.
> So from this, it can identify *total bytes* hold by snapshots (exclusively) =
> sum(all snapshot pending bytes)
>
> Gap:
> * newly pending for delete in active db can be part of snapshots, this will
> not be able to be treated as snapshot exclusive till additional computation
> is done for this.
> * This might be not in this scope
> * This will be treated as pending bytes, but recon when doing seggregation
> can handle this scenario.
>
> As implementation perspective, it can be implemented during -
> * deep clean service of snapshot
> * store this information in SnapshotInfoTable
>
