[jira] [Created] (HBASE-26809) Report client backoff time for server overloaded in ConnectionMetrics

Bryan Beaudreault created HBASE-26809:
-----------------------------------------

             Summary: Report client backoff time for server overloaded in ConnectionMetrics
                 Key: HBASE-26809
                 URL: https://issues.apache.org/jira/browse/HBASE-26809
             Project: HBase
          Issue Type: New Feature
            Reporter: Bryan Beaudreault


Servers can throw CallQueueTooBigException and CallDroppedException when overloaded. As of HBASE-26807, these can have a configurable extra backoff to allow the server to recover. Depending on the server side queue implementation, different callers may be more or less impacted by server load. It is very useful to measure in the client how much time is spent backing off so we can see which clients are most affected by server overload.
