Вы будете получать автодополнение кода даже там, где вы считали это невозможным раньше.

along with the applicable date(defaults to time of initiating the reset). All objects created prior to this date are eligible for re-replication if existing object replication is enabled for the replication rule the object satisfies. At the time of completion of replication, `x-minio-internal-replication-reset-arn:<arn>` is set in the metadata with the timestamp of replication and ResetID. For saving iops, the objects which are re-replicated are not first set to `PENDING` state.
