-------------------------------------
Summary: Try spin lock for MVCC completion
Key: HBASE-15047
URL: https://issues.apache.org/jira/browse/HBASE-15047
Project: HBase
Issue Type: Bug
Reporter: Elliott Clark
Assignee: Elliott Clark
Waits/Notify is very very expensive since it can cost a thread scheduling.
There should only ever be a few threads ( < Num Cores ) running. So it should
be possible to spin and use compare and swap to update the read point.
