## 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)

|

Use client tools like `mc` to set and listen for event notifications using the [`event` sub-command](https://min.io/docs/minio/linux/reference/minio-mc/mc-event-add.html). MinIO SDK's [`BucketNotification` APIs](https://min.io/docs/minio/linux/developers/go/API.html#setbucketnotification-ctx-context-context-bucketname-string-config-notification-configuration-error) can also be used. The notification message MinIO sends to publish an event is a JSON message...

workloads rely on HDFS atomic rename functionality to complete writing data to the datastore. Object storage operations are atomic by nature and they do not require/implement rename API. The default S3A committer emulates renames through copy and delete APIs. This interaction pattern causes significant loss of performance because of the write amplification. _Netflix_, for example, developed two new staging committers - the Directory staging committer and the Partitioned staging committer - to take full...

Install the necessary dependencies.
```sh
pip install flask requests
```

Following is an example lambda handler.
```py
from flask import Flask, request, abort, make_response
import requests

app = Flask(__name__)
@app.route('/', methods=['POST'])
def get_webhook():
	if request.method == 'POST':
		# obtain the request event from the 'POST' call
		event = request.json

		object_context = event["getObjectContext"]
