> Currently, SyncThread made a checkpoint too frequently, which affects
> performance. data is writing to entry logger file might be blocked by syncing
> same entry logger file, which affect bookie to achieve higher throughput. We
> could schedule checkpoint only when rotating an entry log file. so new
> incoming entries would be written to newer entry log file and old entry log
> file could be synced.
