PySpark is the Python API for Apache Spark. PySpark enables developers to write Spark applications using Python, providing access to Spark’s rich set of features and capabilities through Python language. With its rich set of features, robust performance, and extensive ecosystem, PySpark has become a popular choice for data engineers, data scientist...
The following are the main features of PySpark. 1. Python API: PySpark provides a Python API for interacting with Spark, enabling Python developers to leverage Spark’s distributed computing capabilities. 2. Distributed Computing: PySpark utilizes Spark’s distributed computing framework to process large-scale data across a cluster of machines, enabl...
PySpark architecture consists of a driver program that coordinates tasks and interacts with a cluster manager to allocate resources. The driver communicates with worker nodes, where tasks are executed within an executor’s JVM. SparkContext manages the execution environment, while the DataFrame API enables high-level abstraction for data manipulatio...

PySpark RDD (Resilient Distributed Dataset)is a fundamental data structure of PySpark that is fault-tolerant, immutable, and distributed collections of objects. RDDs are immutable, meaning they cannot be changed once created. Any transformation on an RDD results in a new RDD. Each dataset in RDD is divided into logical partitions, which can be comp...
A DataFrame is a distributed dataset comprising data arranged in rows and columns with named attributes. It shares similarities with relational database tables or R/Python data frames but incorporates sophisticated optimizations. If you come from a Python background, I would assume you already know what Pandas DataFrame is. PySpark DataFrame is mos...
PySpark SQLis a module in Spark that provides a higher-level abstraction for working with structured data and can be used SQL queries. PySpark SQL enables you to write SQL queries against structured data, leveraging standard SQL syntax and semantics. This familiarity with SQL allows users with SQL proficiency to transition to Spark for data process...
PySpark Streaming Tutorial for Beginners – Spark streaming is used to process real-time data from sources like file system folders, TCP sockets, S3, Kafka, Flume, Twitter, and Amazon Kinesis. The processed data can be pushed to databases, Kafka, live dashboards e.t.c
PySpark MLlib is Apache Spark’s scalable machine learning library, offering a suite of algorithms and tools for building, training, and deploying machine learning models. It provides implementations of popular algorithms for classification, regression, clustering, collaborative filtering, and more. MLlib is designed for distributed computing, allow...
