## How to enable Fan-Out Uploads ?

Fan-Out uploads are automatically enabled if `x-minio-fanout-list` form-field is provided with the PostUpload API, to keep things simple higher level APIs are provided in our SDKs for example in `minio-go` SDK:

```
PutObjectFanOut(ctx context.Context, bucket string, fanOutContent io.Reader, fanOutReq minio.PutObjectFanOutRequest) ([]minio.PutObjectFanOutResponse, error)

- Acquire TLS certificates, either from a CA or [create self-signed certificates](https://min.io/docs/minio/kubernetes/upstream/operations/network-encryption.html).

```
~ mc admin config set alias/ scanner
KEY:

Refer [Prometheus documentation](https://prometheus.io/docs/introduction/first_steps/) for more details.

### 2. Configure authentication type for Prometheus metrics

MinIO supports two authentication modes for Prometheus either `jwt` or `public`, by default MinIO runs in `jwt` mode. To allow public access without authentication for prometheus metrics set environment as follows.

```
export MINIO_PROMETHEUS_AUTH_TYPE="public"
minio server ~/test
```

- Greater than or equal to 2, if `REDUCED_REDUNDANCY` parity is not set.
- Greater than `REDUCED_REDUNDANCY` parity, if it is set.

Parity blocks can not be higher than data blocks, so `STANDARD` storage class parity can not be higher than N/2. (N being total number of drives)

The default value for the `STANDARD` storage class depends on the number of volumes in the erasure set:

| Erasure Set Size | Default Parity (EC:N) |

points to the public IP address where each cluster might be accessible, this is unique for each cluster.

NOTE: `mybucket` only exists on one cluster either `cluster1` or `cluster2` this is random and
is decided by how `domain.com` gets resolved, if there is a round-robin DNS on `domain.com` then
it is randomized which cluster might provision the bucket.

### 3. Test your setup

        </ExcludedPrefixes>

        <!-- .. up to 10 prefixes in all -->
</VersioningConfiguration>
```

In the above sample config, objects under prefixes matching any of the `ExcludedPrefixes` glob patterns will neither be versioned nor replicated.

### SSE-C Encryption

MinIO does not support SSE-C encrypted objects on replicated buckets, any application uploading SSE-C encrypted objects will be rejected with an error on replicated buckets.

export MINIO_COMPRESSION_MIME_TYPES="text/*,application/json,application/xml"
```

> [!NOTE]
> To enable compression for all content when using environment variables, set either or both of the extensions and MIME types to `*` instead of an empty string:
> ```bash
> export MINIO_COMPRESSION_ENABLE="on"
> export MINIO_COMPRESSION_EXTENSIONS="*"
> export MINIO_COMPRESSION_MIME_TYPES="*"
> ```

### 1. Prerequisites

Install MinIO either on Kubernetes or Distributed Linux.
