> 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.
