## NOTE

- Empty delete markers (such as for objects with no other successor versions) do not transition to the new pool to avoid creating empty metadata on the other pool(s). If you believe transitioning empty delete markers is required, open a GitHub issue.

### Idempotent versions on delete markers

Duplicate delete markers are not created on MinIO buckets with versioning, if an application performs a soft delete on an object repeatedly - that object will only ever have a single DELETE marker for all such successive attempts. This is done to ensure that repeated soft deletes do not ever need multiple versions in the first place.

It must be noted that if active-active replication is set up with delete marker replication, there is potential for duplicate delete markers to be created if both source and target concurrently set a Delete Marker or if one/both of the clusters went down at tandem before the replication event was synced.This is an unavoidable side-effect in active-active replication caused by allowing delete markers set on a object version with `REPLICA` status back to source.

      purge:
          # retainVersions: 0 # (default) delete all versions of the object. This option is the fastest.
          # retainVersions: 5 # keep the latest 5 versions of the object including delete markers.

  notify:
    endpoint: https://notify.endpoint # notification endpoint to receive job completion status
    token: Bearer xxxxx # optional authentication token for the notification endpoint
  
  retry:

public class PrecommitTask extends DefaultTask {

    @OutputFile
    public File getSuccessMarker() {
        return new File(getProjectLayout().getBuildDirectory().getAsFile().get(), "markers/" + this.getName());
    }

    @TaskAction
    public void writeMarker() throws IOException {
        Files.write(getSuccessMarker().toPath(), new byte[] {}, StandardOpenOption.CREATE);
    }

    ]
}

### 3.3 Automatic removal of delete markers with no other versions

When an object has only one version as a delete marker, the latter can be automatically removed after a certain number of days using the following configuration:

```
{
    "Rules": [
        {
            "ID": "Removing all delete markers",
            "Expiration": {
                "ExpiredObjectDeleteMarker": true

        .include("**")
        // exclude sh files that might have the executable bit set
        .exclude("**/*.sh");

    private File outputMarker = new File(getProject().getBuildDir(), "markers/filePermissions");

    @Inject
    public FilePermissionsTask(ProjectLayout projectLayout) {
        this.projectLayout = projectLayout;
        setDescription("Checks java source files for correct file permissions");

    DependencyResolutionResult getDependencyResolutionResult();

    // for each exception
    // - knowing what artifacts are missing
    // - project building exception
    // - invalid project model exception: list of markers
    // - xmlpull parser exception
    List<Throwable> getExceptions();

    MavenExecutionResult addException(Throwable e);

    boolean hasExceptions();
