Welcome to This PySpark Tutorial!
This is the base tutorial page of the PySpark from where you can explore all about the PySpark.PySpark is a popular interface for accessing the Apache Spark features with the Python Programming Language. So, If you come from a core Python background and want to make your career in Big Data, Data Science, or Data Engineering, you can start to learn PySpark.
Before knowing PySpark Let’s understand the difference between PySpark and Spark.

What is Apache Spark?
Apache Spark is an open-source popular big data processing framework. Apache Spark is written in Scala programming language. Apache Spark is most used in Data engineering, data science, and machine learning on single or clusters.
Key features of Apache Spark:
- Batch/Streaming Data:- We can perform batch or streaming processing. The difference between batch processing and streaming processing is that In batch processing data comes to perform processing periodically but in streaming processing data comes continuously to perform processing.
- We can use our preferred language to process that data.
- SQL Analytics:- Apache Spark also allows to perform SQL queries to get the reporting for dashboarding.
- Machine learning:- Spark provides an MLlib module to perform machine learning operations.
Let’s move on to the PySpark.
What is PySpark?
PySpark is nothing but an interface written in Python programming just like another package to interact with Apache Spark. Using PySpark APIs our application can use all the functionalities of Apache Spark to process large-scale datasets and perform operations on top of loaded datasets.
Who Can Learn PySpark?
If you come from a Python background and you want to build your career in the Data domain then definitely you can go with PySpark because it is just an interface like other Python packages that you can use for Data processing and data engineering purposes.
Here I have listed all the tutorials related to PySpark that will be helpful in your PySpark journey.
