Spark Tutorial

Apache spark is one of the largest open-source projects used for data processing. Spark is a lightning-fast and general unified analytical engine in big data and machine learning. It supports high-level APIs in a language like JAVA, SCALA, PYTHON, SQL, and R. It was developed in 2009 in the UC Berkeley lab, now known as AMPLab. As spark is the engine used for data processing, it can be built on top of Apache Hadoop, Apache Mesos, and Kubernetes, standalone, and on the cloud like AWS, Azure, or GCP, which will act as data storage.

Apache spark has its own stack of libraries like Spark SQL, DataFrames, Spark MLlib for machine learning, and GraphX graph computation. Streaming this library can be combined internally in the same application.

Why Do We Need to Learn Spark?

In today’s era, data is the new oil, but data exists in structured, semi-structured, and unstructured forms. Apache Spark achieves high performance for batch and streaming data. Big internet companies like Netflix, Amazon, Yahoo, and Facebook have started using spark for deployment and using a cluster of around 8000 nodes to store petabytes of data. Technology is moving ahead daily, and to keep up with the same Apache spark is a must. Below are some reasons to learn:

Spark is 100 times faster in memory than MapReduce, and it can integrate with the Hadoop ecosystem easily; hence the use of spark is increasing in big and small companies. Moreover, as it is open-source, most organizations have already implemented spark.

Data is generated from mobile apps, websites, IOTs, sensors, etc., and this huge data is difficult to handle and process. Spark provides real-time processing of this data. Furthermore, spark has speed and ease of use with Python and SQL language; hence most machine learning engineers and data scientists prefer spark.

Spark programming can be done in Java, Python, Scala, and R, and most professional or college student has prior knowledge. Prior knowledge helps learners create spark applications in their known language. Also, the scale at which spark has developed is supported by Java. Also, 100-200 lines of code written in Java for a single application can be converted to

Spark professional has a high demand in today’s market, and the recruiter is ready to bend some rules by providing a high salary to spark developers. As there are high demand and low supply in Apache spark professionals, It is the right time to get into this technology to earn big bucks.

Applications of Spark

Apache spark ecosystem is used by industry to build and run fast big data applications. Here are some applications of sparks:

In Financial Services: Apache spark analysis can be used to detect fraud and security threats by analyzing a huge amount of archived logs and combining this with external sources like user accounts, and internal information Spark stack could help us to get top-notch results from this data to reduce risk in our financial portfolio

Pre-requisites

To learn Apache Spark programmer needs prior knowledge of Scala functional programming, Hadoop framework, Unix Shell scripting, RDBMS database concepts, and Linux operating system. Apart from this, knowledge of Java can be useful. If one wants to use Apache PySpark, then python knowledge is preferred.

Target Audience

The Apache spark tutorial is for analytics and data engineering professionals. Also, professionals aspiring to become Spark developers by learning spark frameworks from their respective fields, like  ETL developers and Python Developers, can use this tutorial to transition into big data.
