------------------------------------
Summary: Have the datanode heartbeat include queued command counts (was:
Have the datanode heartbeat include queue command counts)
> Have the datanode heartbeat include queued command counts
> ---------------------------------------------------------
>
> Key: HDDS-6554
> URL: https://issues.apache.org/jira/browse/HDDS-6554
> Project: Apache Ozone
> Issue Type: Improvement
> Components: Ozone Datanode
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
>
> To allow SCM to make better decisions about scheduling commands on datanodes,
> the datanodes should report their current command queue size in the
> heartbeat. This change adds a section to the heartbeat protobuf message to
> allow the queued command count for each command type to be reported in each
> heartbeat.
> There will be a count reported for each registered command, with a zero count
> if the queue is empty.
> A followup change will be needed to use this information on SCM. With this
> Jira in place, the data will be sent but never used on SCM.
