Piotr Nowojski commented on FLINK-17571: ---------------------------------------- [~stevenz3wu] maybe another command to remove files for given checkpoint, taking into account that some shared files might not be removed? Btw, it might be usefull [~klion26] to have some reverse mapping as well. A command that would show, to which checkpoints given file(s) belong (unless there is already a way to know it). > A better way to show the files used in currently checkpoints > ------------------------------------------------------------ > > Key: FLINK-17571 > URL: https://issues.apache.org/jira/browse/FLINK-17571 > Project: Flink > Issue Type: New Feature > Components: Runtime / Checkpointing > Reporter: Congxian Qiu(klion26) > Priority: Major > > Inspired by the > [userMail|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|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}} -- This message was sent by Atlassian Jira (v8.3.4#803005)
