HiveQL can be also be applied. PySparkSQL is a wrapper over the PySpark core. PySparkSQL introduced the DataFrame, a tabular representation of structured data that is similar to that of a table from a relational database management system.

Use Cases

Batch processing
PySpark RDD and DataFrame’s are used to process batch pipelines where you would need high throughput.
Realtime processing
PySpark Streaming is used to for real time processing.
Machine Learning
PySpark ML and MLlib is used for machine learning.
Graph processing
PySpark GraphX and GraphFrames are used for Graph processing.
