Every company today wants to crunch numbers and learn what its data is hiding. The patterns and trends that data show can have a huge impact on the marketing strategies and quality of products and services that the company offers to its customer base. But, before they start analyzing trends, data is captured, stored, and cached.
Where is the data cached and stored? How is it stored? How can companies ensure that their marketers, researchers, and other team members have access to relevant data as and when required? All this and more is possible with the help of Apache Spark.
The following article will help you understand what is Spark, as well as the average Spark salary across various states of India. It will also shed light on a Spark developer job description and the required skill set that every Spark developer is expected to have.
What is Apache Spark?
Technically, it is an open-source, distributed, cluster-computing framework that is written in Java. Apache Spark is a data-processing engine that is used for caching data of several petabytes. The cached data is stored across multiple operations to facilitate interactive querying; quickly and securely. The data processing framework performs tasks and distributes data across multiple computers.
Spark can work on its own or in collaboration with other distributed computing tools to determine the nodes and sequence of the execution of tasks. Spark databases are used by every major industry in the world, including tech industries, BFSI sector, e-commerce, iGaming and sports companies, education institutes, telecommunication companies, and even governments. Most Data Scientists and Data Engineers work with Spark.

Features Of Apache Spark
Now that you have a basic understanding of what is Spark, let’s take a look at some of the top features of this technology that make it so popular in the business world.
- Fast Processing- When it comes to Big Data, speed is one of the most important components. Big Data, which is characterised by its volume and variety, needs to be processed at a higher speed. This is where Apache spark comes into play. With the help of this technology, you can now process Big Data almost ten to one times faster than other technologies such as Hadoop. Spark’s ability can be attributed to the Resilient Distributed Dataset, which helps reduce the time consumption of basic tasks such as reading and writing operations.
- Flexibility- Yet another feature of Apache spark that makes it highly desirable is that it can support multiple languages. This means that developers can now write applications in different languages, such as Java, Python, or Scala, without the need to confirm to only one specific language.
- Real-time Processing- Contrary to most other technologies that only use stored data, Apache spark allows real-time data processing. This means that you can now get instant outcomes with the help of Apache Spark.
- Enhanced Analytics- Last but not least, Apache Spark is equipped with various features, such as complex analytics and machine learning algorithms, that can enhance the performance of analytics much faster and more efficiently.
All these features undoubtedly make Apache Spark one of the most sought-after technologies. With that said, let’s take a look at some of the use cases of this technology.
Use Cases Of Apache Spark
Be it the financial sector or the healthcare industry, the use cases of Apache Spark have grown manifold over the years. More and more industries have switched to this technology to perform advanced analytics. One such example might include Yahoo, which relies heavily on Apache Spark to curate personalized content for its users. Simultaneously, other enterprises such as Nickelodeon and MTV have also been able to successfully harness the power of Apache Spark to enhance their customer experience. Before moving on to the Spark developer job description, here are some of the top use cases of Apache Spark.
- Financial Sector- In the financial sector, Apache Spark is mainly used to put forward new financial products to their target consumers. Furthermore, this technology also allows business owners to understand customer behaviour, by analysing their movements on various social media platforms. This, in turn, helps them to identify the key issues of the said users in a much more efficient and faster manner.
- Healthcare Industry- Apache Spark especially bores quite huge responsibilities in the healthcare industry, as with the help of this technology, professionals try to put together the past clinical data of a patient, along with their current one, to get a more comprehensive picture.
- Manufacturing and Retail- Last but not least, Apache Spark is also heavily used in both manufacturing and retail industries to provide personalised services to their customers.
With that said, let’s take a closer look at the average Spark salary all over India, as well as the Spark developer job description mentioned below.

What is the difference between Apache Hadoop and Apache Spark?
Apache Hadoop is a general-purpose distributed system which handles large data. It has several components such as HDFS, MapReduce, and YARN. On the other hand, Apache Spark is an open-source tool which uses RAM for processing data. The two have considerable differences. Hadoop is an open-source platform, and hence it is less expensive compared to Apache Spark, which relies on RAM and, hence, increases costs. Hadoop is suitable for batch processing, while Spark is good for interactive analysis. Hadoop can enable data processing in batch mode only, while Spark has the advantage of processing real-time data.
What do you mean by Veracity in Hadoop?
As the name suggests, veracity is related to the accuracy and trustworthiness of the data. Data veracity refers to the various issues with data such as biasedness, the reliability of data sources, noise in the data, accuracy of data, etc. It is one of the most essential characteristics of the Hadoop system. It also involves processing, analysing, and interpreting the data in the desired way to yield meaningful results. However, it may sometimes get difficult to track the data source and quality when multiple datasets are combined. Hence, veracity is one area which still needs improvement.
What languages are supported by Apache Spark?
Apache Spark is a fast, open-source operating system. It supports 4 languages: Scala, Java, Python, and R. All of these languages have several pros and cons based on which developers choose their preferred language. Writing code in Scala and Python is comparatively easier than writing in Java. Scala processes and analyses data 10 times faster than that of Python and is more maintainable than Python, a statistically-typed language. Due to these reasons, Scala is the most popularly used programming language for Spark. On the other hand, Python is preferred over Scala in machine learning because it has advanced tools for Data Science and Machine Learning. You should choose a language based on your experience and comfort.
