-----------------------------------------
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.
