Are you confused whether Python is important for your data analysis or not? Then, through this blog you will get a gist of how and why you should use Pyspark to carry out the analysis.

What is PySpark?

PySpark is an open-source Python and  Apache Spark application programming interface  (API). You can perform large data analytics and quick processing for datasets of any size using this well-liked data science platform. To make data processing and data analysis more accessible, it combines the speed and performance of Apache Spark with the ease of use of Python. This includes working with big data sets and machine learning methods.
Based on information from Statista, the globe produced and used an anticipated 120 zettabytes of data in 2023, compared to 97 zettabytes the previous year. By 2025, the amount is expected to increase to 181 zettabytes according to the Global Statistics Platform. Given the crucial role that it plays in artificial intelligence (AI), professionals who can efficiently organize, analyze, and process it will have an advantage. This is where PySpark shines.
PySpark is compatible with all of Spark’s features, including DataFrames, Machine Learning (MLlib), Structured Streaming, Spark SQL, and Spark Core. Additionally, PySpark allows you to connect with Java virtual machine (JVM) objects, perform streaming computation and stream processing, and switch between Apache Spark and Pandas. It can be used with external libraries such as PySparkSQL, which simplifies handling large volumes of data, and GraphFrames, which is useful for effective graph analysis.

How to install PySpark?

Prior to setting up  PySpark  and Apache Spark on your device, the following software needs to be installed:


Follow Python developer setup instructions to install Python if it isn’t already installed before moving on to the next step.


Next, if you’re using Windows, follow this tutorial to install Java on your machine. Here are installation instructions for  Linux  and  MacOSX , respectively.

Jupyter Notebook

You can write code and see equations, graphics, and text in an online application called Jupyter Notebooks. Among data scientists, it is one of the most often used programming editors. Make sure you have Jupyter Notebook installed, as we will be writing all of the PySpark code for this lesson using it.

Why PySpark?

PySpark is a popular framework among businesses due to its speedy large processing capabilities. It can process its bigger volumes and is faster than frameworks like Pandas and Dask. For example, Pandas and Dask would not function if you had to process its petabytes of, whereas PySpark would be able to manage it with ease.
Although Python code may also be written on top of a distributed system such as Hadoop, many businesses prefer to use Spark and its PySpark API since Spark is faster and can handle real-time data. While Hadoop can only handle it in batch mode, PySpark allows you to create code to collect it from a continually updated source.
In actuality, Apache Flink is a more performant distributed processing solution than Spark, and it offers a Python API named PyFlink. But Apache Spark is more dependable because it has been around for a longer time and has stronger community support.
Furthermore, PySpark offers fault tolerance, which enables it to recover from sustained losses as a result of failures. The framework is kept in random access memory (RAM) and features in-memory computing as well. It can function on a computer without an SSD or hard drive installed.

Features of PySpark
  1. Ease of Use : Simple programming abstraction offered by PySpark makes it easy for developers to implement sophisticated processing jobs in Python. It makes use of Spark’s distributed processing capabilities while retaining Python’s ease of use and adaptability.
  2. Speed : PySpark’s underlying engine, Spark, is renowned for its swiftness. It uses improved query execution plans and in-memory computing to achieve excellent performance. PySpark is suited for efficiently processing big datasets because it inherits this speed.
  3. Distributed Processing : PySpark enables users to grow their  applications  horizontally by facilitating distributed processing across several cluster nodes. Transparently managing parallel execution, it distributes workloads around the cluster to achieve optimal performance.
  4. Rich Libraries : SQL, streaming, machine learning (MLlib), graph processing (GraphX), and other processing activities are all made possible by PySpark’s comprehensive library collection. With the help of these libraries, users can carry out a variety of analytics tasks without integrating other technologies.
  5. Integration with Python environment:  PySpark easily interacts with the Python environment, enabling users to use well-known Python libraries for data analysis, visualization, and manipulation in Spark applications, including Pandas, NumPy, Matplotlib, and scikit-learn.
  6. Fault Tolerance:  PySpark includes built-in fault tolerance to make sure that calculations can withstand errors. By using data replication and lineage information, it achieves fault tolerance, enabling it to recover gracefully from failures without sacrificing data integrity.
  7. Interactive Shell:  Before implementing their processing logic in production, users can interactively explore and prototype it with PySpark’s interactive shell (PySpark Shell), which is akin to the Python REPL (Read-Eval-Print Loop).
  8. Extensibility : The great extensibility of PySpark enables users to incorporate unique functions, libraries, and data sources into Spark applications. With the use of third-party extensions, user-defined functions (UDFs), and custom aggregations, users can customize PySpark to meet their unique needs.
  9. Community Support:  PySpark has a sizable and vibrant user and  development  community. The community makes it simple for new users to get started with PySpark and for seasoned users to solve issues by offering assistance, documentation, tutorials, and contributed libraries.
