Jufang He commented on FLINK-33856:
-----------------------------------
[~Jiang Xin] Yes, this metrics optimization has been implemented in our
company, which is very helpful for locating checkpoint bottlenecks. Now I want
to contribute to the community, can you assign this to me?
> Add metrics to monitor the interaction performance between task and external
> storage system in the process of checkpoint making

> Key: FLINK-33856
> URL: https://issues.apache.org/jira/browse/FLINK-33856
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Checkpointing
> Affects Versions: 1.18.0
> Reporter: Jufang He
> Priority: Major
>
> 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.
