   yes，I know that data is written to the system cache first, but eventually it is written to disk.And FlushConsumeQueueService is also executed asynchronously。
   If it's to ensure data is written to disk, why not use filechannel.force.&nbsp;
   
   
   Or write to mappedbytebuffer like commitlog.

   fileChannel.write does not directly write ByteBuffer data to disk
