Spark is an Apache project advertised as “lightning fast cluster computing”. It has a thriving open-source community and is the most active Apache project at the moment. Spark provides a faster and more general data processing platform. Spark lets you run programs up to 100x faster in memory, or 10x faster on disk, than Hadoop.

1. Apache Spark Terminologies – Objective. This article cover core Apache Spark concepts, including Apache Spark Terminologies. Ultimately, it is an introduction to all the terms used in Apache Spark with focus and clarity in mind like Action, Stage, task, RDD, Dataframe, Datasets, Spark session etc. Apache Spark is so popular tool in big data, it provides a powerful and unified engine to Introduction to the Apache Spark software library that is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models.

Introduction to Data Analysis for . And I just wanted to give a call out to the previous three sessions, three workshops. Spark SQL is a component on top of Spark Core that introduced a data abstraction called DataFrames, which provides support for structured and semi-structured data. Spark SQL provides a domain-specific language (DSL) to manipulate DataFrames in Scala, Java, Python or .NET. Spark SQL Datasets: In the version 1.6 of Spark, Spark dataset was the interface that was added. The catch with this interface is that it provides the benefits of RDDs along with the benefits of optimized execution engine of Apache Spark SQL. Apache Spark is a In Memory Data Processing Solution that can work with existing data source like HDFS and can make use of your existing computation infrastructure like YARN/Mesos etc. This talk will cover a basic introduction of Apache Spark with its various components like MLib, Shark, GrpahX and with few examples.
