> {{CompletedCheckpoint.DiscardObject.discard}} is not implemented in an idempotent fashion because we're losing the operatorState even in the case of a failure (see [CompletedCheckpoint:328|https://github.com/apache/flink/blob/dc419b5639f68bcb0b773763f24179dd3536d713/flink-runtime/src/main/java/org/apache/flink/runtime/checkpoint/CompletedCheckpoint.java#L328]). This prevents us from retrying the deletion.
