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.
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.
Who is a Spark Developer?
A Spark Developer is a software developer with Apache Spark skills. While Android Developers help to write code for a new app, Spark Developers create code to ensure that Big Data is available – it is all about ensuring the relevant data is available in the shortest time possible when a query is raised.
The Apache Spark Developers have a deep understanding of Java and Scala language. Technical expertise for concepts related to object-oriented programming helps the Developers to optimize performance and distribution.
