@vsair @zhouxinyu another config flushCommitLogTimed has already handled
such situation, and avoided SSD write amplification.
If flushCommitLogTimed is enabled, it will only wakeup the
commitLogService, but could not wakeup the flushCommitLogService, for:
```
if (flushCommitLogTimed) {
Thread.sleep(interval);
} else {
this.waitForRunning(interval);
}
```---
