Introduction
Apache Spark is an open-source, general-purpose, multi-language analytics engine for large-scale data processing. It works on both single and multiple nodes by utilizing the RAM in clusters to perform fast data queries on large amounts of data. It offers batch data processing and real-time streaming, with support of high-level APIs in languages such as Python, SQL, Scala, Java or R. The framework offers in-memory technologies that allow it to store queries and data directly in the main memory of the cluster nodes.
This article explains how to install Apache Spark on Ubuntu 20.04 server.
