Hi @somramsam, if you use the delete command (adding to your user the role "can_delete") you make the deleted data unsearchable, but they remain in the buckets. If instead you use the CLI command or you modify index retention, data will be physically removed. Remember that if you modify retention, data will be removed as a bucket, in other words you could still have data older than the retention period because they are in a bucket containing some data still in the retention period; the bucket will be removed whan the latest event exceeds the retention period.
