> When Flink makes a checkpoint, the interaction performance with the external 
> file system has a great impact on the overall time-consuming. Therefore, it 
> is easy to observe the bottleneck point by adding performance indicators when 
> the task interacts with the external file storage system. These include: the 
> rate of file write , the latency to write the file, the latency to close the 
> file.
> In flink side add the above metrics has the following advantages: convenient 
> statistical different task E2E time-consuming; do not need to distinguish the 
> type of external storage system, can be unified in the 
> FsCheckpointStreamFactory.
