//
		// import org.apache.spark.sql.SparkSession
		// import org.apache.spark.sql.types.{IntegerType, StringType, StructField, StructType}
		// object SparkJSONRead {
		//   def main(args: Array[String]): Unit = {
		//     val spark:SparkSession = SparkSession.builder()
		//       .appName("SparkByExample")
		//       .master("local[1]").getOrCreate()

### Step 3: Test on NATS

If you use NATS server, check out this sample program below to log the bucket notification added to NATS.

```go
package main

// Import Go and NATS packages
import (
 "log"
 "runtime"

 "github.com/nats-io/nats.go"
)

func main() {

 // Create server connection
 natsConnection, _ := nats.Connect("nats://yourusername:yoursecret@localhost:4222")
 log.Println("Connected")

	// Add Content-Length
	req.ContentLength = contentLength

	return req, nil
}

// Various signature types we are supporting, currently
// two main signature types.
type signerType int

const (
	signerV2 signerType = iota
	signerV4
)
