	3. Call one of the methods on `SqlQuery` to actually run the query

Simple Scala method to print RDD content in Spark

	// To be able to easily print RDD content, you can either create a function inside the shell or an implicit class
	// Ref to my answer: http://stackoverflow.com/a/41317574/1095213

	def p(rdd: org.apache.spark.rdd.RDD[_]) = rdd.foreach(println) // Option 1

	implicit class Printer(rdd: org.apache.spark.rdd.RDD[_]) { // Option 2
	def print = rdd.foreach(println)
	}

	// Example

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
