> EC: Notify ReplicationManager when a heartbeat updates datanode command counts
> ------------------------------------------------------------------------------

> Key: HDDS-7471
> URL: https://issues.apache.org/jira/browse/HDDS-7471
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: SCM
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
> Labels: pull-request-available
>
> When a datanode heartbeat is processed, it updates the queued command counts
> on the datanodes. Replication is going to use this information when assigning
> work to datanodes, and if a datanode exceeds the load limit it will be
> excluded until it has more capacity.
> To allow RM to remove nodes from any exclude lists, we should fire a SCM
> event when the counts are updated, as this will avoid RM polling frequently.
> For now, the notification in RM does not do anything - we will add code which
> uses it in future changes as we build out the load aware under / over
> replication processing.
