-------------------------------------------
Summary: Codel lifoThreshold should be applied on soft queue limit
instead of hard limit
Key: HBASE-29912
URL: https://issues.apache.org/jira/browse/HBASE-29912
Project: HBase
Issue Type: Bug
Components: rpc
Affects Versions: 2.5.13, 2.6.4, 3.0.0-beta-1
Reporter: Umesh Kumar Kumawat
Assignee: Umesh Kumar Kumawat
For now codel lifoThreshold is applied on hard limit. By default soft limit of
the queue remains 100 (10 handler per queue
(CALL_QUEUE_HANDLER_FACTOR_CONF_KEY) and we use
DEFAULT_MAX_CALLQUEUE_LENGTH_PER_HANDLER is 10). And 250 is hard limit.
This way we are never achiving out desired behaviour.
