```

Gets or sets a value indicating whether obsolete checkpoint blobs are deleted after a new checkpoint is published. Defaults to true.

## GetCheckpointBlobName {#getcheckpointblobname-f25c4754}

```csharp
public int MaxMetadataOnlyConflictRetries
```

Gets or sets the maximum number of times a journaling Append, Replace, or Delete operation will refresh its cached WAL ETag and retry in place after observing a metadata-only ETag conflict (for example, a concurrent caller-owned metadata update or generation bump). When the cap is exceeded the storage layer falls back to throwing [InconsistentStateException](/orleans/docs/api/csharp/microsoft.orleans.core/orleans.storage.inconsistentstateexception/) and the journaling layer recovers before retrying. Defaults to 5.

## MetadataOnlyConflictInitialBackoff {#metadataonlyconflictinitialbackoff-d86202a4}

[Dedicated page](/orleans/docs/api/csharp/microsoft.orleans.journaling.azurestorage/orleans.journaling.azureblobjournalstorageoptions/properties/metadataonlyconflictinitialbackoff-d86202a4/)

```csharp
public TimeSpan MetadataOnlyConflictInitialBackoff
```

Gets or sets the initial delay applied before re-trying after a metadata-only ETag conflict. Subsequent attempts double the delay (capped at [AzureBlobJournalStorageOptions](/orleans/docs/api/csharp/microsoft.orleans.journaling.azurestorage/orleans.journaling.azureblobjournalstorageoptions/)). Set to `System.TimeSpan.Zero` to retry immediately without backoff. Defaults to 10 ms.

## MetadataOnlyConflictMaxBackoff {#metadataonlyconflictmaxbackoff-2339b91a}

[Dedicated page](/orleans/docs/api/csharp/microsoft.orleans.journaling.azurestorage/orleans.journaling.azureblobjournalstorageoptions/properties/metadataonlyconflictmaxbackoff-2339b91a/)

```csharp
public TimeSpan MetadataOnlyConflictMaxBackoff
```

Gets or sets the upper bound on the per-attempt backoff used by metadata-only conflict retries. The exponential schedule starts at [AzureBlobJournalStorageOptions](/orleans/docs/api/csharp/microsoft.orleans.journaling.azurestorage/orleans.journaling.azureblobjournalstorageoptions/) and never exceeds this value. Defaults to 200 ms.
