Bug Fix and Enhancements

We have also squashed a few bugs and added few enhancements in this release. Here are some of the highlighting fixes & enhancements.

  • Fix High Memory Usage Issue: Some of our users were seeing spike in memory usage by Stash backup process after upgrading to Stash v2021.06.23. We have fixed the issue in this release. Your memory usage should be stable again after upgrading to v2021.08.02.
  • Support Kubernetes 1.22.x: We have upgraded the underlying libraries to support Kubernetes 1.22.x. Now, Stash should work flawlessly with Kubernetes 1.22.x.
  • Fix Region Issue with S3 Backend: Some of our users were facing issues with custom region in S3 backend. We have fixed this issue. Now, Stash should work with custom region for S3 and S3 compatible backends.
  • Added Duration Column: We have added DURATION column in kubectl get output for BackupSession and RestoreSession. You can now check how much time it took to complete the backup and restore process directly in kubectl get output. Here, is an example:
# BackupSession
❯ kubectl get backupsession -n demo
NAME                             INVOKER-TYPE          INVOKER-NAME          PHASE       DURATION    AGE
sample-redis-backup-1627490702   BackupConfiguration   sample-redis-backup   Succeeded   1m18s       89s

# RestoreSession
❯ kubectl get restoresession -n demo -w
NAME                   REPOSITORY   PHASE       DURATION     AGE
