-------------------------------------
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.
