One of the most well-liked fields of the twenty-first century is data science. Companies use Data Scientists to help them better understand the market and improve their products. Data scientists act as decision-makers and are primarily responsible for analyzing and processing large amounts of structured and unstructured data. They need different tools and programming languages for data science to do this. Including Apache Spark – The most popular software for data science that we will analyze in detail shortly.

Overview of Apache Spark software

What is Apache Spark?

Apache Spar is an integrated analytics engine for large-scale data processing. Apache Spark achieves high performance for both batch data and streaming data, using a modern DAG scheduler, query optimizer, and physical execution engine. Spark provides more than 80 high-level operators that make it easy to build parallel applications.

Apache Spark has many features that make it a great choice as a big data processing engine. Many of these features establish Apache Spark’s advantage over other Big Data processing engines. Let’s take a detailed look at some of the key features that differentiate it from the competition.

  • Fault Tolerance: Apache Spark is built to handle failed worker nodes. It achieves this fault tolerance by using DAG and RDD (Elastic Distributed Dataset).
  • Real-time Stream Processing: Spark Streaming brings Apache Spark’s language integration API into stream processing, allowing you to write streaming tasks the same way you write batch tasks.
  • Fast Speed: Spark enables applications to run up to 100x faster in memory and up to 10x faster on disk. Spark achieves this by using a DAG, a query optimizer, and a highly optimized physics execution engine.
  • Advanced Analytics: Apache Spark has quickly become the de facto standard for big data processing and data science in many industries. Spark provides both machine learning and graph processing libraries, which companies across sectors leverage to solve complex problems. And all this is made easy using the power of Spark and highly scalable cluster computers.
  • Multi-language support: Spark has built-in multi-language support. The majority of the Java, Scala, Python, and R APIs are present. The R language for data analysis also comes with more sophisticated features.
  • Cost Savings: Apache Spark is open-source software, so it doesn’t have any licensing fees associated with it. Users only need to worry about hardware costs. Also, Apache Spark reduces a lot of other overhead because it has built-in stream processing, ML, and Graph processing.
  • Integration with Hadoop: Spark can run standalone and also on top of Hadoop YARN Cluster Manager and thus it can read existing Hadoop data. Therefore, Spark is very flexible.

Apache Spark- The most popular software for data science

General Features

One of the most powerful features of Apache Spark is generality. Built with a wide range of capabilities and features, it empowers users to deploy many different types of data analysis that they can aggregate in one tool.

Easily query structured data

Apache Spark contains a module called Spark SQL that users can use to write and execute SQL queries so that they can work and process structured data in Apache Spark-related programs.

Access data from different sources

Using SQL queries and the DataFrame API, users can establish a uniform and standard way of accessing data coming from multiple data sources. This means that no matter how diverse the data collection sources are, Apache Spark ensures that users can adopt a common method for connecting to sources.

Accelerated stream data processing

Apache Spark is equipped with a component built specifically to accelerate the processing of stream data called Spark Streaming and is one of the libraries available in the system. Spark Streaming allows users to connect different data sources as well as access real-time data streams.

Using high-level machine learning algorithms

Another highlight of Apache Spark is the use of high-performance algorithms included in the machine learning library or MLlib. Using these algorithms, users can perform and deploy computational tasks and tasks hundreds of times faster than Map/Reduce and provide high-performance iterability.

Easy graph analysis

Apache Spark provides users with a graph processing system, called GraphX, that allows for performing smarter and more efficient graph computation and analysis in one engine. Using GraphX, users can visualize the data they have in the form of a graph, and then convert a set of edges and vertices into a graph.

Create streaming apps

With Spark Streaming, users will be able to create scalable, fault-tolerant, and interoperable streaming applications and programs. As they build such applications, they can write and trigger streaming tasks and jobs within the applications using high-level operators.


After considering the above features, it can be easily said that Apache Spark is the most popular and advanced Apache product for Big Data processing. It has different modules for machine learning, structured and unstructured data streaming and processing. Therefore, Apache Spark is considered the most popular software for data science.
