Let me first explain what is Spark Eco-System. This will help you in gaining better insights. Apache Spark Architecture is based on two main abstractions:īut before diving any deeper into the Spark architecture, let me explain few fundamental concepts of Spark like Spark Eco-system and RDD. This architecture is further integrated with various extensions and libraries. It also provides a shell in Scala and Python.Īpache Spark has a well-defined layered architecture where all the spark components and layers are loosely coupled. Spark code can be written in any of these four languages. Spark provides high-level APIs in Java, Scala, Python, and R. It offers Real-time computation & low latency because of in-memory computation. It can be deployed through Mesos, Hadoop via YARN, or Spark’s own cluster manager. Simple programming layer provides powerful caching and disk persistence capabilities. It is also able to achieve this speed through controlled partitioning. Spark runs up to 100 times faster than Hadoop MapReduce for large-scale data processing. Features of Apache Spark: Fig: Features of Spark It is designed to cover a wide range of workloads such as batch applications, iterative algorithms, interactive queries, and streaming. Spark provides an interface for programming entire clusters with implicit data parallelism and fault tolerance. The main feature of Apache Spark is its in-memory cluster computing that increases the processing speed of an application. In this Spark Architecture article, I will be covering the following topics:Īpache Spark is an open source cluster computing framework for real-time data processing. In this blog, I will give you a brief insight on Spark Architecture and the fundamentals that underlie Spark Architecture. According to Spark Certified Experts, Sparks performance is up to 100 times faster in memory and 10 times faster on disk when compared to Hadoop.
