>
> Enhance ReplicationManager to calculate a Datanode's load factor using its
> current queue and the effective replication limit (including
> outofservice.limit.factor). Modify ECUnderReplicationHandler to dynamically
> switch from 1-1 replication to reconstruction when a source Datanode's load
> exceeds the threshold. Implement "source offloading" logic to ensure that
> when reconstruction is triggered, the SCM prefers healthy replicas on other
> nodes as sources, bypassing the bottlenecked node.
