Summary: Fastpath for the FIFO rpcscheduler
Key: HBASE-16023
URL: https://issues.apache.org/jira/browse/HBASE-16023
Project: HBase
Issue Type: Sub-task
Components: Performance
Reporter: stack
Assignee: stack
This is an idea copied from kudu where we skip queuing a request if there is a
handler ready to go; we just do a direct handoff from reader to handler.
Makes for close to a %20 improvement in random read workloadc testing moving
the bottleneck to HBASE-15716 and to returning the results.
