Spark SQL is the core module in Spark, while Presto is in the Hadoop ecosystem. Se hela listan på databricks.com Spark SQL was added to Spark in version 1.0. Shark was an older SQL-on-Spark project out of the University of California, Berkeley, that modified Apache Hive to run on Spark. It has now been replaced by Spark SQL to provide better integration with the Spark engine and language APIs.

In this section, we will show how to use Apache Spark SQL which brings you much closer to an SQL style query similar to using a relational database. We will once more reuse the Context trait which we created in Bootstrap a SparkSession so that we can have access to a SparkSession..
