[jira] [Created] (ZOOKEEPER-3690) Improving leader efficiency via not processing learner's requests in commit processor

Fangmin Lv created ZOOKEEPER-3690:
-------------------------------------

             Summary: Improving leader efficiency via not processing learner's requests in commit processor
                 Key: ZOOKEEPER-3690
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3690
             Project: ZooKeeper
          Issue Type: Improvement
            Reporter: Fangmin Lv
            Assignee: Fangmin Lv


Currently, all the requests forwarded from learners will be processed like the locally received requests from leader's clients, which is non-trivial effort and not necessary to process those in CommitProcessor with session queue create/destroy

To improve the efficiency, we could skip processing those requests in leader's commit processor. Based on the benchmark, this optimization improved around 30% maximum write throughput for read/write mixed workload.
