Apache Storm vs Spark Streaming – Feature wise Comparison 13

1. Objective This tutorial will cover the comparison between Apache Storm vs Spark streaming. Apache Storm is the stream processing engine for processing real-time streaming data. While Apache Spark is general purpose computing engine. It provides Spark Streaming to handle streaming data. It process data in near real-time. Let’s understand which is better in the battle of Spark vs storm. 2. Apache Storm vs Spark Streaming Comparison The following description shows the detailed feature wise difference between Apache Storm vs Spark […]

Spark RDD – Introduction, Features & Operations of RDD

1. Objective RDD (Resilient Distributed Dataset) is the fundamental data structure of Apache Spark which are an immutable collection of objects which computes on the different node of the cluster. Each and every dataset in Spark RDD is logically partitioned across many servers so that they can be computed on different nodes of the cluster. In this blog, we are going to get to know about what is RDD in Apache Spark. What are the features of RDD, What is […]

Introduction to Apache Spark RDD Operations - Transformtions and Actions API with Example.

Spark RDD Operations-Transformation & Action with Example

1. Objective Two types of Apache Spark RDD operations are- Transformations and Actions. A Transformation is a function that produces new RDD from the existing RDDs but when we want to work with the actual dataset, at that point Action is performed. When the action is triggered after the result, new RDD is not formed like transformation. In this Apache Spark RDD operations tutorial we will get the detailed view of what is Spark RDD, what is the transformation in Spark […]
