Congxian Qiu(klion26) updated FLINK-17571:
------------------------------------------
Description:
Inspired by the [user
mail|[http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Shared-Checkpoint-Cleanup-and-S3-Lifecycle-Policy-tt34965.html]]
Currently, there are three types of directory 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}}
