Apache Spark is a distributed processing engine that is open source and used for large data applications. It is capable of handling batch as well as legitimate analytics and data processing workloads. Apache Spark is an engine that can handle hundreds of terabytes of data on thousands of nodes and is used to speed up lots of tasks. Apache Spark is a dynamic engine that can process more than 100,000 independent tasks at the same time. It is said to be superior to MapReduce because it allows you to run sequential data processing and has a dynamic query processing model that makes it easier for you to manage data and use a larger amount of randomness in your data. This reduces latency and improves performance.

Apache Spark was developed by Matei Zaharia when he was working on his PhD thesis at UC Berkeley. In 2010, Matei Zaharia founded Databricks, a company that is now behind Spark. Since then, many companies have adopted Apache Spark as a part of their big data solution. Some of these companies are Walmart, Yahoo, IBM, and Sony, to name a few. Many universities are also training students in Apache Spark technology. Apache Spark can be used for machine learning applications like Recommendation engines and Graph analysis. It can also be used in streaming analytics by ingesting large amounts of log data but processing it in real-time.

Apache Beam vs Spark

Apache Beam seems more like a framework since it isolates processing complexity and conceals technological specifics. On the other hand, Spark is an approach to process parallelism and offers a general platform for developing computational workflows. Beam seems oriented toward machine-learning applications, while Spark is more of a general-purpose computing tool. Both Apache Beam and Spark are unified frameworks. They enable different data processing engines (e.g., SQL, Java, Python, etc.) to run together through a single programming interface. For example, Beam and Spark allow you to use the SQL engine as the driver of a Java or Python code intended for data science tasks. Both technologies support creating complex workflows through directed graphs with various elements of parallelism and control flow.
