Take note this feature is at present marked Experimental and is meant for advanced customers. It might get replaced in upcoming with read/compose assist based upon Spark SQL, in which scenario Spark SQL is the popular tactic.
We call SparkSession.builder to construct a SparkSession, then set the appliance title, and finally simply call getOrCreate to obtain the SparkSession instance.
