Thus, it is a useful addition to the core Spark API. Spark Streaming is the component of Spark which is used to process real-time streaming data. It is responsible for memory management and fault recovery, scheduling, distributing and monitoring jobs on a cluster & interacting with storage systems. Further, additional libraries which are built on the top of the core allows diverse workloads for streaming, SQL, and machine learning. Spark Core is the base engine for large-scale parallel and distributed data processing. Spark Eco-SystemĪs you can see from the below image, the spark ecosystem is composed of various components like Spark SQL, Spark Streaming, MLlib, GraphX, and the Core API component. 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. It does many things good but nothing great.Apache Spark is an open-source cluster computing framework which is setting the world of Big Data on fire. We like the helpful tips scattered throughout, but ultimately, we feel Sparks spreads itself a little too thin. While we applaud Sparks for being a one-stop solution, the lack of refinement and overwhelming number of options make it difficult for newbies to fully grasp its power. Podcasts can be played from within Sparks or they can be added to your default media player.

The final tab acts a download manager of sorts, displaying all of your downloaded media files. The Internet radio tab works in a similar fashion, with a large directory of stations divided by country.
The built-in RSS reader works well, and the nice tree-style directory makes navigating feeds simple.

While this feature does work, tweaking and arranging items is frustrating since Sparks lacks a full visual display and basic editing tools. Sparks provides a recording mode for creating your own podcasts. And while that's all fine and well, this jack-of-all-trades isn't really a master of anything.ĭespite its overwhelming functionality, Sparks is fairly easy to navigate thanks to the helpful tabs that differentiate the focus areas of the program. Sparks takes an interesting approach by tackling both of these mediums, as well as Internet radio and RSS. The past year has seen some exciting developments courtesy of the Internet, mostly notably blogs and Podcasting.
