             Summary: Do not hold the RaftConsensus lock while performing I/O
                 Key: KUDU-2175
                 URL: https://issues.apache.org/jira/browse/KUDU-2175
             Project: Kudu
          Issue Type: Improvement
            Reporter: Mike Percy


Do not hold the RaftConsensus lock while performing I/O. This optimization would improve stability and reliability as it could make a tablet server less sensitive to disk latency spikes and election storms. On the other hand, we would need to carefully ensure that the ordering invariants currently enforced by this lock continue to hold.
