## 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)

Sample handler:
```go
    handler :=  func(payload []byte) ([]byte, *grid.RemoteErr) {
        // Do something with payload
        return []byte("response"), nil
    }

    err := manager.RegisterSingleHandler(grid.HandlerDiskInfo, handler)
```

Sample call:
```go
    // Get a connection to the remote host
    conn := manager.Connection(host)

Note that transition event notification is a MinIO extension.

with values `REDUCED_REDUNDANCY` or `STANDARD`, MinIO server uses default parity values.

### Set metadata

In below example `minio-go` is used to set the storage class to `REDUCED_REDUNDANCY`. This means this object will be split across 6 data drives and 2 parity drives (as per the storage class set in previous step).

```go
s3Client, err := minio.New("localhost:9000", "YOUR-ACCESSKEYID", "YOUR-SECRETACCESSKEY", true)
if err != nil {
 log.Fatalln(err)

### Using WebIdentiy API

On another terminal run `web-identity.go` a sample client application which obtains JWT id_tokens from an identity provider, in our case its Keycloak. Uses the returned id_token response to get new temporary credentials from the MinIO server using the STS API call `AssumeRoleWithWebIdentity`.
