This session covers the most important concept of Spark framework which is SPARK SQL. Spark SQL allows us to query structured data inside Spark programs, using SQL or a DataFrame API which can be used in Java, Scala, Python and R. To run the streaming computation, developers simply write a batch computation against the DataFrame / Dataset API, and Spark automatically increments the computation to run it in a streaming fashion.
