"You can also use the module to execute SQL queries as you would with a relational database." ("Fetching And Persisting Bitcoin Market Data" section)

I frequently use this to explore data in ORC files using SQL queries:

val df ="gs://[bucket and path I am reading ORC files from]")
val df.createOrReplaceTempView("[viewName]")
spark.sql("SELECT * FROM [viewName] WHERE ...").show(false)
