---------------------------------------
Summary: Have the datanode heartbeat include queue 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
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.
