---------------------------------------
please also consider https://issues.apache.org/jira/browse/HDDS-16220 as an
additional control that should be introduced.

> *Problem*
> OM's background block deletion ({{{}KeyDeletingService{}}} →
> {{{}ScmBlockLocationProtocol.deleteKeyBlocks{}}}) writes transactions into
> SCM's Ratis-replicated {{{}DeletedBlockLog{}}}. When SCM followers lag the
> leader, this async load is exactly what backs up, but OM has no lag-aware
> throttle today — only static limits.
