When should one use connection pooling in node.js mysql?

This is the typical way I create MySQL connection in node.js 

var connection = mysql.createConnection({
  host     : 'localhost',
  user     : 'root',
  password : '',
  database : 'address_book'
});
var app = express();

connection.connect(function(err){
if(!err) {
    console.log("Database is connected ... nn");    
} else {
    console.log("Error connecting database ... nn");    
}
});

Is it good enough for production use? When should one use connection pooling? What are the advantages and disadvantages of using connection pooling?

This will work but creating mysql connection for each and every request is not recommended.

So it would be better to have a pool of mysql connections, as cost of getting a connection will be nil compared to prior case.
