Apache Sparkis an in-memory distributed data processing engine that is used for processing and analytics of large data-sets. Spark presents a simple interface for the user to perform distributed computing on the entire cluster. Spark does not have its own file systems, so it has to depend on the storage systems for data-processing. It can run on HD...
The traditional way of processing data on Hadoop is using its MapReduce framework. MapReduce involves a lot of disk usage and as such the processing is slower. As data analytics became more main-stream, the creators felt a need to speed up the processing by reducing the disk utilization during job runs. Apache Spark addresses this issue by performi...
Credit: https://spark.apache.org/ Spark Core uses a master-slave architecture. The Driver program runs in the master node and distributes the tasks to an Executor running on various slave nodes. The Executor runs on their own separate JVMs, which perform the tasks assigned to them in multiple threads. Each Executor also has a cache associated with ...
We have discussed a lot about Spark and its architecture, so now let's take a look at a simple Spark job which counts the sum of space-separated numbers from a given text file: We will start off by importing the dependencies for Spark Core which contains the Spark processing engine. It has no further requirements as it can use the local file-system...
Apache Spark is the platform of choice due to its blazing data processing speed, ease-of-use, and fault tolerant features. In this article, we took a look at the architecture of Spark and what is the secret of its lightning-fast processing speed with the help of an example. We also took a look at the popular Spark Libraries and their features.
