How to do real-time data processing in sparksql?
- In SparkSQL, real-time data processing is not possible directly. We can register the existing RDD as a SQL table and trigger the SQL queries on priority.
What is Spark SQL?
- Spark SQL was released in May 2014, and is now one of the most actively developed components in Spark. As of this writing, Apache Spark is the most active open source project for big data processing, with over 400 contributors in the past year. Spark SQL has already been deployed in very large scale environments.
What are the functions associated with spark for data processing?
- There are several functions associated with Spark for data processing such as custom transformation, spark SQL functions, Columns Function, User Defined functions known as UDF. Spark defines the dataset as data frames. It helps to add, write, modify and remove the columns of the data frames.
