## How to enable Fan-Out Uploads ?

```
mc admin user add myminio newuser newuser123
```

Once the user is successfully created you can now apply the `getonly` policy for this user.

```
mc admin policy attach myminio getonly --user=newuser
```

### 3. Create a new group

```
mc admin group add myminio newgroup newuser
```

Once the group is successfully created you can now apply the `getonly` policy for this group.

```

description will be provided once it's integrated into presubmit.

### test_import_api_packages

This Python test verifies whether the API v2 packages can be imported from the
current build. It utilizes the `_api/v2/api_packages.txt` list of packages from
the local wheel file specified in the `requirements_lock_<python_version>.txt`.

Packages are imported one by one in alphabetical order during runtime.

You can create and run multiple 'replication' jobs at a time there are no predefined limits set.

## Batch Jobs Terminology

### Job
A job is the basic unit of work for MinIO Batch Job. A job is a self describing YAML, once this YAML is submitted and evaluated - MinIO performs the requested actions on each of the objects obtained under the described criteria in job YAML file.

### Type

```
mc admin tier add s3 source S3TIER --bucket s3bucket --prefix testprefix/ --use-aws-role
```

- Once object lock configuration is set to a bucket
  - New objects inherit the retention settings of the bucket object lock configuration automatically
  - Retention headers can be optionally set while uploading objects
  - Once objects are uploaded PutObjectRetention API can be called to change retention settings

```
mc admin policy attach myminio userManager adminManageUser.json
```

Create a new admin user `admin1` on MinIO use `mc admin user`.

```
mc admin user add myminio admin1 admin123
```

Once the user is successfully created you can now apply the `userManage` policy for this user.

```
mc admin policy attach myminio userManager --user=admin1
```

               AEAD <- key, nonce + 0    AEAD <- key, nonce + 1    AEAD <- key, nonce + 2    ...

Once the config changes are applied, proceed to restart **Hadoop** services.

#### 3.2 Public Prometheus config

If Prometheus endpoint authentication type is set to `public`. Following prometheus config is sufficient to start scraping metrics data from MinIO.
This can be collected from any server once per collection.

##### Cluster

```yaml
scrape_configs:
- job_name: minio-job
  metrics_path: /minio/v2/metrics/cluster
  scheme: http
  static_configs:
  - targets: ['localhost:9000']
```
