> Key: FLINK-27051
> URL: https://issues.apache.org/jira/browse/FLINK-27051
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Coordination
> Affects Versions: 1.15.0
> Reporter: Matthias Pohl
> Priority: Major
>
> {{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.
