stack commented on HBASE-15146: ------------------------------- Patch LGTM. We only decrement when we get to max queue size. Were you going to add another place to decrement? > Don't block on Reader threads queueing to a scheduler queue > ----------------------------------------------------------- > > Key: HBASE-15146 > URL: https://issues.apache.org/jira/browse/HBASE-15146 > Project: HBase > Issue Type: Bug > Affects Versions: 1.2.0 > Reporter: Elliott Clark > Assignee: Elliott Clark > Priority: Blocker > Fix For: 1.2.0 > > Attachments: HBASE-15146.0.patch, HBASE-15146.1.patch, > HBASE-15146.2.patch, HBASE-15146.3.patch, HBASE-15146.4.patch > > > Blocking on the epoll thread is awful. The new rpc scheduler can have lots of > different queues. Those queues have different capacity limits. Currently the > dispatch method can block trying to add the the blocking queue in any of the > schedulers. > This causes readers to block, tcp acks are delayed, and everything slows down. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
