[~stack] sure, would like to make it open. The indent here is to help prevent / mitigate call queue buildups and associated latency spikes in case of either sudden increase of traffic rate, or sudden decrease in available request throughput (raid card/disk issue, kernel lockup etc). So, thorough test of this patch include two things - checking that performance doesn't degrade in normal conditions (since locking was changed a bit), and verifying behavior in case of various kinds of failures. I'll post more data as we roll it out. > Explore different queuing behaviors while busy > ---------------------------------------------- > > Key: HBASE-15136 > URL: https://issues.apache.org/jira/browse/HBASE-15136 > Project: HBase > Issue Type: New Feature > Components: IPC/RPC > Reporter: Elliott Clark > Assignee: Mikhail Antonov > Fix For: 2.0.0, 1.3.0 > > Attachments: HBASE-15136-1.2.v1.patch, HBASE-15136-v2.patch, deadline_scheduler_v_0_2.patch > > > http://queue.acm.org/detail.cfm?id=2839461 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
