--------------------------------------
Currently, working on some urgent things in my company, just unassign the
ticket from me. anyone else is interested in this can take over it.
If no one working on this and I find some time, will come back :)
There is a WIP branch https://github.com/klion26/flink/tree/FLINK-17571
> A better way to show the files used in currently checkpoints

> Currently, there are [three types of
> directory|https://ci.apache.org/projects/flink/flink-docs-release-1.10/ops/state/checkpoints.html#directory-structure]
> for a checkpoint, the files in TASKOWND and EXCLUSIVE directory can be
> deleted safely, but users can't delete the files in the SHARED directory
> safely(the files may be created a long time ago).
> I think it's better to give users a better way to know which files are
> currently used(so the others are not used)
> maybe a command-line command such as below is ok enough to support such a
> feature.
> {{./bin/flink checkpoint list $checkpointDir # list all the files used in
> checkpoint}}
