Is there a module to implement sql in spark? How does it work?..

Answer / Kuldeep Kumar

Yes, there is a module to implement SQL in Apache Spark. It's called Spark SQL. When using Spark SQL, you can register DataFrames as temporary tables and perform SQL operations on them using SparkSession. The execution plan for SQL queries involves conversion of the queries into a logical plan, then a physical plan, and finally an execution plan.
