Here we see that MinIO performed `HSET` on `minio_events` key.

In case, `access` format was used, then `minio_events` would be a list, and the MinIO server would have performed an `RPUSH` to append to the list. A consumer of this list would ideally use `BLPOP` to remove list items from the left-end of the list.

## Publish MinIO events via NATS

Install NATS from [here](http://nats.io/).

### Step 1: Add NATS endpoint to MinIO

	// Use buffered channel to take care of burst sends or slow w.Write()
	ch := make(chan event.Event, globalAPIConfig.getRequestsPoolCapacity())

	return makeTestTargetURL(endPoint, bucketName, prefix, queryValue)

// return URL for listing objects in the bucket with V2 API.
