Assignee: Priyesh K
> Pass usedBytes in Delete blocktransaction from OM to SCM
> --------------------------------------------------------

> Key: HDDS-13178
> URL: https://issues.apache.org/jira/browse/HDDS-13178
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Priyesh K
> Assignee: Priyesh K
> Priority: Major
>
> Currently, during block deletion, OM sends a {{DeletedBlocksTransaction}} to
> SCM containing only the list of {{{}BlockID{}}}s to be deleted. However, this
> lacks block-level size information, making it difficult for SCM to compute
> accurate metrics on pending deletions and total space that will be reclaimed.
> Introduce two new proto messages:
> * {{DeletedBlock}} – contains {{BlockID}} and corresponding {{usedBytes}}
> * {{DeletedBlockGroup}} – contains {{groupId}} and list of {{DeletedBlock}}
> {{}}
> Also required corresponding proto changes in SCM
