Answer / Satish Chandra
"Spark SQL is a module in Apache Spark that allows data to be manipulated using SQL queries or DataFrames API. It provides an optimized execution engine for high-level and flexible data manipulation, allowing users to execute SQL queries on structured and semi-structured data. Spark SQL also integrates with Hive and can use Hive's metastore for managing schemas.".
